NAME

       tin, rtin - related files

DESCRIPTION

       This  man  page describes the various (config) files and their formats used by the tin(1) newsreader. All
       files are expected to have unix style ('\n' aka LF) line endings.

FILES

       $MAILCAPS
       ~/.mailcap
       /etc/mailcap
       /usr/etc/mailcap
       /usr/local/etc/mailcap
       /etc/mail/mailcap

              mailcap(5) files as defined in RFC1524. The mailcap files are read by tin(1) to determine  how  to
              display  non-text  messages  at  the local site. Any line that starts with "#" is a comment. Blank
              lines are ignored. Otherwise, each line defines a single mailcap entry for a single content  type.
              Long lines may be continued by ending them with a backslash character, "\".

              Each  individual mailcap entry consists of a content-type specification, a command to execute, and
              (possibly) a set of optional "flag" values.

              The "type" field is simply any legal content type name. It is the  string  that  will  be  matched
              against  the  ''Content-Type:''  header  to  decide  if this is the mailcap entry that matches the
              current message. Additionally, the type field may specify a subtype or a  wildcard  to  match  all
              subtypes.

              The  "command" field is any UNIX command and is used to specify the interpreter for the given type
              of message. It will be passed to the shell via the system(3) facility.

              Semicolons and backslashes within the command or any flag field must be quoted  with  backslashes.
              If  the  field  contains  "%s",  those  two characters will be replaced by the name of a file that
              contains the body of the message. If it contains "%t", those two characters will  be  replaced  by
              the content-type field, including the subtype, if any. If it contains "%{" followed by a parameter
              name  and  a  closing  "}",  then  all those characters will be replaced by the value of the named
              parameter, if any, from the ''Content-Type:'' header. Finally, if the field contains  "\%",  those
              two characters will be replaced by a single "%" character.

              Besides the type and command field the following "flags" are defined:

              compose
                     The "compose" field may be used to specify a program that can be used to compose a new body
                     or body part in the given format. Its intended use is to support mail composing agents that
                     support  the composition of multiple types of mail using external composing agents. As with
                     the view-command, the semantics of program execution are operating  system  dependent.  The
                     result  of  the composing program may be data that is not yet suitable for mail transport —
                     that is, a Content-Transfer-Encoding may need to be applied to the data.

              composetyped
                     The "composetyped" field is similar to the "compose" field, but is  to  be  used  when  the
                     composing  program needs to specify the ''Content-Type:'' header field to be applied to the
                     composed data. The "compose" field is simpler, and is preferred for use with existing (non-
                     mail-oriented) programs for composing data in a given format. The "composetyped"  field  is
                     necessary  when  the  Content-Type  information  must include auxiliary parameters, and the
                     composition program must then know  enough  about  mail  formats  to  produce  output  that
                     includes the mail type information.

              edit   The  "edit"  field may be used to specify a program that can be used to edit a body or body
                     part in the given format. In many cases, it may be identical in content  to  the  "compose"
                     field, and shares the operating-system dependent semantics for program execution.

              print  The  "print"  field may be used to specify a program that can be used to print a message or
                     body part in the given format. As with the view-command, the semantics of program execution
                     are operating system dependent.

              test   The "test"  field  may  be  used  to  test  some  external  condition  (e.g.,  the  machine
                     architecture,  or  the  window  system in use) to determine whether or not the mailcap line
                     applies. It specifies a program to  be  run  to  test  some  condition.  The  semantics  of
                     execution  and of the value returned by the test program are operating system dependent. If
                     the test fails, a subsequent mailcap entry should be sought. Multiple test fields  are  not
                     permitted — since a test can call a program, it can already be arbitrarily complex.

              needsterminal
                     The  "needsterminal"  field  indicates  that the view-command must be run on an interactive
                     terminal. This is needed to inform window-oriented user agents that an interactive terminal
                     is needed. (The decision is not left  exclusively  to  the  view-command  because  in  some
                     circumstances  it  may not be possible for such programs to tell whether or not they are on
                     interactive terminals.) The needsterminal command should be assumed to apply to the compose
                     and edit commands, too, if they exist. Note that this is NOT a test - it is  a  requirement
                     for  the  environment in which the program will be executed, and should typically cause the
                     creation of a terminal window when not executed on either a real  terminal  or  a  terminal
                     window.

              copiousoutput
                     The  "copiousoutput"  field  indicates  that  the  output  from the view-command will be an
                     extended stream of output, and is to be interpreted as advice to the UA (User  Agent  mail-
                     reading  program)  that the output should be either paged or made scroll-able. Note that it
                     is probably a mistake if needsterminal and copiousoutput are both specified.

              description
                     The "description" field simply provides a  textual  description,  optionally  quoted,  that
                     describes the type of data, to be used optionally by mail readers that wish to describe the
                     data before offering to display it.

              textualnewlines
                     The "textualnewlines" field, if set to any non-zero value, indicates that this type of data
                     is  line-oriented  and  that,  if  encoded  in  base64, all newlines should be converted to
                     canonical form (CRLF) before encoding, and will be in that form after decoding. In general,
                     this field is needed only if there is line-oriented data of some type other than text/*  or
                     non-line- oriented data that is a subtype of text.

              x11-bitmap
                     The  "x11-bitmap"  field  names  a  file,  in  X11  bitmap (xbm) format, which points to an
                     appropriate icon to be used to visually denote the presence of this kind of data.

              nametemplate
                     The "nametemplate" field gives a filename format, in which %s will be replaced by  a  short
                     unique  string  to give the name of the temporary file to be passed to the viewing command.
                     This is only expected  to  be  relevant  in  environments  where  filename  extensions  are
                     meaningful,  e.g.,  one  could  specify that a GIF file being passed to a gif viewer should
                     have a name ending in ".gif" by using "nametemplate=%s.gif"

              tin(1)  currently  only  respects  the  "test",  "description",  "nametemplate"  and  partly   the
              "needsterminal"  flags,  all other flags are internally ignored. It also can't handle the "%F" and
              "%n" expansions yet.

              Example:
                     # mailcap file example
                     image/*;\
                        xv -8 -geometry +0 '%s';\
                        description=%{name} %t-Image;\
                        test=test "$DISPLAY" != "";\
                        nametemplate=%s.IMAGE

                     message/rfc822;\
                        ${PAGER:-"more"} '%s';\
                        edit=${EDITOR:-"vi"} '%s';\
                        compose=${EDITOR:-"vi"} '%s';\
                        print=a2ps '%s';\
                        needsterminal

       /etc/news/server

              default NNTP-server to read news  from  if  not  reading  from  the  local  spool.   '-g  server',
              $NNTPSERVER  have  higher  priority  (in that order), the default server given at compile time has
              lower priority.

       ${TIN_HOMEDIR:-"$HOME"}/.cancelsecret

              secret to be used for cancel-locks if tin(1) is built with support for it. An  empty  secret  file
              disables the cancel-lock creation in that case. This file should be readable only by the user.

       ${TIN_HOMEDIR:-"$HOME"}/.mime.types
       /etc/mime.types
       /etc/tin/mime.types

              mime type / filename extension pairs

       ${TIN_HOMEDIR:-"$HOME"}/.newsauth

              "nntpserver[:port]  password  [user]"  pairs  for NNTP servers that require authorization.  If the
              password contains a space or a tab it must be enclosed in double quotes (").  Usernames  must  not
              be enclosed in double quotes and thus can't contain spaces or tabs.  Any line that starts with "#"
              is  a  comment.   Blank  lines  are ignored.  This file should be readable only for the user as it
              contains the user's unencrypted password for reading news!

              nntpserver
                     full qualified domain name of the news server. Additionally, a port  can  be  specified  by
                     appending :portnumber.

              password
                     user's unencrypted password for reading news.

              user   username on the news server if it differs from the local login. This field is optional.

              Example:
                     # sample .newsauth file
                     news.example.org  secret
                     news.example.net  arcane  guest
                     news.example.com  "top secret"  james.bond@example.com

       ${TIN_HOMEDIR:-"$HOME"}/.newsrc

              "newsgroupflag [article[,article | -article]...]"  lines.

              newsgroup
                     the name of the newsgroup.

              flag   a flag indicating if the group is subscribed ':' or not '!'.

              article
                     range of already read articles from that group; numbers separated by commas with sequential
                     numbers  collapsed with hyphens. Empty lines and lines which start with "#" are ignored and
                     not written back.

              Example:
                     # sample .newsrc file
                     news.software.b! 1-666,669

              saved newsgroups index files

       ${TIN_HOMEDIR:-"$HOME"}/.tin/active.mail

              active file ("mailgroupname maxnum minnum mailspool" quadruples) of  user's  mailgroups  (requires
              tin(1) to be built with mh-mail-handling support).

              mailgroupname
                     must be the pathname of the mailbox relative to field #4 with '/' changed to '.'

              maxnum just put a large number here, something higher than the highest message in the mailbox

              minnum put 0 here

              mailspool
                     path of mail spool directory. This must be the full pathname to the root of the mail folder
                     area.

              Example:
                     Mail.inbox  12345 00000 /home/foo
                     Mail.outbox 23456 00000 /home/foo

              This  allows  access  to  the  'inbox'  and  'outbox'  folders of user foo.  They are accessed via
              /home/foo/Mail/inbox and /home/foo/Mail/outbox

       ${TIN_HOMEDIR:-"$HOME"}/.tin/active.save

              active file of user's saved newsgroups, used by tin -R.

       /etc/tin/attributes
       ${TIN_HOMEDIR:-"$HOME"}/.tin/attributes

              The  group  attributes   files   may   be   used   to   override   some   global   settings   from
              ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc  on a per group basis. Order is important as last match counts;
              this allows one to refine attributes for narrowed scopes. Note that the scope=<grouplist> line has
              to be specified before the attributes are specified for that list and each attribute can  only  be
              set  once  per  scope  section. All attributes are set to a reasonable default so you only have to
              specify the attribute that you want to change. All toggle attributes are set by specifying ON/OFF.
              Otherwise, they function exactly as their global equivalents. The following group  attributes  are
              available:

              scope  This  changes  the  list of groups to which the attributes that follow will be applied. See
                     the section NEWSGROUP LISTS & WILDCARDS in tin(1) for the types of pattern that can be used
                     here.

              mime_forward
                     Determines whether usenet articles are forwarded as attachment or inline. When set to  OFF,
                     the forwarded article will be included in the body of the mail, while setting this variable
                     to  ON will cause the article to be attached as a separate MIME part. Enabling mime_forward
                     is particularly useful for articles consisting of multiple  MIME  parts  such  as  PGP/MIME
                     signed  messages  or  being encoded in a different character set than your local one. It is
                     also useful if the receiver should be able to  operate  on  the  entire  forwarded  article
                     (i.e.,  view  or  save it without your comments). On the other hand, if you want to forward
                     only some parts of the article or to insert 'inline' annotations, you might want to disable
                     this option.  Currently mime_forward is forced if the article to be attached is a multipart
                     MIME article, this may change in a future version.  Please note that  for  this  option  to
                     have  effect,  the  tinrc  variable  interactive_mailer  has  to  be set to 0 (which is the
                     default).

              mime_types_to_save
                     A comma separated list of MIME major/minor Content-Types that will be saved when using  the
                     view/save  and save/autosave features.  A single * can be used to wildcard the major and/or
                     minor  type  and  a  !  as  the  first  character  in  an  entry  will   negate   it,   eg:
                     image/*,!image/bmp,!text/html. Default is */*

              organization
                     This  can  be  used  to  set  the  article header field ''Organization:''. It overrides the
                     setting (if any) of organization in /etc/tin/tin.defaults and $ORGANIZATION (or $NEWSORG on
                     Apollo DomainOS). If it points to a readable file a random line  from  that  file  will  be
                     used. Note that some news servers might still overwrite the ''Organization:'' header.

              undeclared_charset
                     Assume (broken) articles without MIME charset declaration have this charset  —  default  is
                     US-ASCII.  This attribute works only on systems with working iconv(3), others might have to
                     compile tin(1) with --disable-mime-strict-charset.

              Example:
                     # include extra headers
                     # assume ISO-8859-1 as charset if no charset is declared

       ${TIN_HOMEDIR:-"$HOME"}/.tin/filter

              The filter file is used to assign scores to certain articles. Based on the score an article can be
              filtered out (hidden) or marked hot. Empty lines or  lines  beginning  with  a  '#'  are  ignored.
              Multiple  matching-rules in the same scope are all applied individually and not only when they all
              hit at the same time (logical OR not AND).

              comment
                     Every entry (rule) in the filter file might get a comment. Multiple lines are allowed  (but
                     only  for  comments  yet). Every line must start with the "comment=" keyword. Comments must
                     appear first in the rule.  Comment lines placed within a rule will be moved to the begin of
                     the next rule. This might be changed in the future. Don't use '#' to mark comments as those
                     lines are ignored and your comments will get lost on the next write of the file.

              group  A comma-separated list of newsgroup patterns in wildmat-style to which  groups  the  filter
                     rule will be applied. This line is mandatory!

              case   0=case-sensitive, 1=case-insensitive

              score  Score value of the rule; can also be one of the magic words "kill" or "hot".

              subj   Match  against  ''Subject:''.  The  matching  type  used  (wildmat or regex) depends on the
                     setting of the tinrc variable wildcard.

              from   Match against ''From:''.  tin(1) converts the contents of the ''From:'' header  to  an  old
                     style  e-mail  address,  e.g.  ''some@body.example  (John  Doe)''  instead  of  ''John  Doe
                     <some@body.example>'', before trying to match the patterns in the filter rule. The matching
                     type used (wildmat or regex) depends on the setting of the tinrc variable wildcard.

              msgid  Match against ''Message-ID:'' and full ''References:''. The matching type used (wildmat  or
                     regex) depends on the setting of the tinrc variable wildcard.

              msgid_last
                     Match  against  ''Message-ID:'' and last ''References:'' entry (direct responses) only. The
                     matching type used (wildmat or  regex)  depends  on  the  setting  of  the  tinrc  variable
                     wildcard.

              msgid_only
                     Match  against  ''Message-ID:''.  The  matching type used (wildmat or regex) depends on the
                     setting of the tinrc variable wildcard.

              refs_only
                     Match against ''References:''. The matching type used (wildmat or  regex)  depends  on  the
                     setting of the tinrc variable wildcard.

              lines  Match against ''Lines:'', <num matches less than, >num matches more than.

              gnksa  Match  against  ''From:'' address parser return codes. <num matches less than, >num matches
                     more than the returned numeric value.  GNKSA_LOCAL_DOMAIN_LITERAL  or  GNKSA_INVALID_DOMAIN
                     are  only  returned  if  disable_gnksa_domain_check is set to false. As the built in domain
                     list is outdated this should be considered carefully.

              xref   Match against ''Xref:'' line. Before any matching is done the line is turned into the  same
                     format  ''Newsgroups:'' has that is it is turned into a comma separated newsgroup list with
                     all other information (i.e.  the article counter) removed. The matching type used  (wildmat
                     or regex) depends on the setting of the tinrc variable wildcard.

              path   Match  against  ''Path:''  line.  This may not work on some servers. The matching type used
                     (wildmat or regex) depends on the setting of the tinrc variable wildcard.

              hide_uue
                     If  set  to  'No'  then  raw  uuencoded data is displayed. If set to 'Yes' then sections of
                     uuencoded data will be shown with a single tag line showing the size and filename (much the
                     same as a MIME attachment).  If set to 'Hide all' then any line that looks  like  uuencoded
                     data  will  be  folded  into a tag line. This is useful when uuencoded data is split across
                     more than one article but can also lead to  false  positives.  This  setting  can  also  be
                     toggled in the article viewer.  Default is 'No'.

              inews_prog
                     Path, name and options of external inews(1).  If you are reading via NNTP the default value
                     is  "--internal" (use built-in NNTP inews), else it is "inews -h". The article is passed to
                     inews_prog on STDIN via '< article'.

              info_in_last_line
                     If ON, show current group description or article subject in the last line (not in the pager
                     and global menu) — ToggleInfoLastLine ('i') toggles setting. This facility is useful as the
                     full width of the screen is available to display long subjects. Default is OFF.

              interactive_mailer
                     If greater than 0 your mailreader will be invoked earlier for reply so you can use more  of
                     its  features (e.g. MIME, pgp, ...). 1 means include headers, 2 means don't include headers
                     (old use_mailreader_i=ON option). 0 turns off usage. This option has to suit mailer_format.
                     Default is 0.

              inverse_okay
                     If ON use inverse video for page headers and URL highlighting.  Default is ON.

              keep_dead_articles
                     If ON keep all failed postings in ${TIN_HOMEDIR:-"$HOME"}/dead.articles besides keeping the
                     last failed posting in ${TIN_HOMEDIR:-"$HOME"}/dead.article. Default is ON.

              kill_level
                     This option controls the processing and display of articles that are killed.  There  are  3
                     options, default is 0 (Kill only unread arts).

                        0  Kill  only unread arts is the 'traditional' behavior of tin(1).  Only unread articles
                           are killed once only by marking them  read.  As  filtering  only  happens  on  unread
                           articles with kill_level set to 0, art_marked_killed and art_marked_read_selected are
                           only shown once. When you reenter the group the mark will be gone.

                        1  Kill  all  arts  &  show  with K will process all articles in the group and therefore
                           there is a processing overhead when using this option. Killed articles  are  threaded
                           as normal but they will be marked with art_marked_killed.

                        2  Kill  all  arts  and  never show will process all articles in the group and therefore
                           there is a processing overhead when using this option. Killed  articles  simply  does
                           not get displayed at all.

              mail_8bit_header
                     Allows  8bit characters unencoded in the header of mail message. Default is OFF. Turning it
                     ON is effective only if mail_mime_encoding is also set to 8bit. Leaving it OFF is safe  for
                     most users and compliant to Internet Mail Standard (RFC5322 and RFC2047). Default is OFF.

              mail_address
                     User's  mail  address  (and  full  name),  if not username@host. This is used when creating
                     articles, sending mail and when pgp(1) signing.

              mail_mime_encoding
                     MIME encoding of the body in mail message, if necessary  (8bit,  base64,  quoted-printable,
                     7bit). Default is quoted-printable.

              mail_quote_format
                     Format  of  quote  line  when  replying  (via  mail)  to  an  article (%A=Address, %D=Date,
                     %F=Fullname+Address, %G=Groupname, %M=Message-ID, %N=Fullname, %C=Firstname,  %I=Initials).
                     Default is "In article %M you wrote:"

              mailbox_format
                     Select one of the following mailbox-formats: MBOXO (default, except on SCO), MBOXRD or MMDF
                     (default  on SCO). See mbox(5) and RFC4155 for more details on MBOXO and MBOXRD and mmdf(5)
                     for more details about MMDF.

              maildir
                     The directory where articles/threads are to be saved in mbox(5)  format.  This  feature  is
                     mainly   for   use   with   the   mutt(1)   mail  program.  It  allows  the  user  to  save
                     articles/threads/groups simply by giving '=' as  the  filename  to  save  to.   Default  is
                     ${TIN_HOMEDIR:-"$HOME"}/Mail.

              mailer_format
                     The  format  string  used  to  create  the  mailer command with parameters that is used for
                     mailing articles to other people. Default is '%M "%T"  <  %F'  (e.g.,  /bin/mail  "iain"  <
                     ~/.article).  The  flexible  format  allows  other  mailers  with  different  command  line
                     parameters to be used such as
                        sendmail -oem -t < %F
                        mutt -s "%S" -- "%T" < %F
                        mutt -H %F
                        claws-mail --compose "mailto:%T?subject=%S&insert=%F"
                     interactive_mailer must be set adequate. The following substitutions are supported:
                        %F              filename
                        %M              default_mailer
                        %S              subject-field
                        %T              to-filed
                        %U              username
                        %%              %

              mark_saved_read
                     If ON mark articles that are saved as read. Default is ON.

              mark_ignore_tags
                     When this is ON, the GroupMarkThdRead ('K'), ThreadMarkArtRead ('K'),  MarkThdUnread  ('Z')
                     at  Group  level  and  MarkArtUnread  ('z') at Thread level functions mark just the current
                     article or thread, ignoring other tagged, (un)read articles. When OFF,  the  same  function
                     presents a menu with choices of the current thread or article, all tagged, unread articles,
                     or nothing.

              metamail_prog
                     Path,  name  and  options of external metamail(1) program used to view non-textual parts of
                     articles.  To use the built-in viewer, set to --internal. This is the  default  value  when
                     metamail(1)  is  not  installed.  Leave it blank if you don't want any automatic viewing of
                     non-textual attachments. The PageViewAttach ('V') command can always be  used  to  manually
                     view any attachments. See also ask_for_metamail.

              mm_charset
                     Charset  supported  locally,  which  is  also  used  for MIME header (charset parameter and
                     charset name in header encoding) in mail  and  news  postings.  If  MIME_STRICT_CHARSET  is
                     defined  at  compile  time,  text  in  charset  other  than  the value of this parameter is
                     considered not displayable and represented  as  '?'.  Otherwise,  all  character  sets  are
                     regarded  as  compatible  with  the  display. If it's not set, the value of the environment
                     variable $MM_CHARSET is used. US-ASCII or compile-time default is used in case  neither  of
                     them  is  defined. If your system supports iconv(3), this option is disabled and you should
                     use mm_network_charset instead.

              mm_network_charset
                     Charset used for  posting  and  MIME  headers;  replaces  mm_charset.   Conversion  between
                     mm_network_charset  and local charset (determined via nl_langinfo(3)) is done via iconv(3),
                     if this function is not available on your system this option is disabled and  you  have  to
                     use mm_charset instead. mm_network_charset is limited to one of the following charsets:
                        US-ASCII,   ISO-8859-{1,2,3,4,5,7,9,10,13,14,15,16},   KOI8-{R,U,RU}  EUC-{CN,JP,KR,TW},
                        ISO-2022-{CN,CN-EXT,JP,JP-1,JP-2}, Big5, UTF-8
                     Not all values might work on your system, see iconv_open(3) for more details. If  it's  not
                     set,  the  value  of the environment variable $MM_CHARSET is used. US-ASCII or compile-time
                     default is used in case neither of them is defined.

              mono_markdash
                     Character attribute of words emphasized like _this_. It  depends  on  your  terminal  which
                     attributes are usable. See also word_h_display_marks and word_highlight.

              mono_markslash
                     Character  attribute  of  words  emphasized  like /this/. It depends on your terminal which
                     attributes are usable. See also word_h_display_marks and word_highlight.

              mono_markstar
                     Character attribute of words emphasized like *this*. It  depends  on  your  terminal  which
                     attributes are usable. See also word_h_display_marks and word_highlight.

              mono_markstroke
                     Character  attribute  of  words  emphasized  like -this-. It depends on your terminal which
                     attributes are usable. See also word_h_display_marks and word_highlight.

              newnews
                     These are internal timers used by tin(1) to keep track of new  newsgroups.  Do  not  change
                     them unless you understand what they are for.

              news_headers_to_display
                     Which  news  headers you wish to see. If you want to see _all_ the headers, place an '*' as
                     this value. This is the only way a wildcard can be used.  If you enter 'X-' as  the  value,
                     you  will  see  all  headers beginning with 'X-' (like X-Alan or X-Pape). You can list more
                     than one by delimiting with spaces. Not defining anything turns off this option.

              news_headers_to_not_display
                     Same as news_headers_to_display except it denotes the opposite. An example  of  using  both
                     options  might  be  if you thought 'X-' headers were A Good Thing(tm), but thought Alan and
                     Pape   were   miscreants...   well   then   you   would    do    something    like    this:
                     news_headers_to_display=X-  news_headers_to_not_display=X-Alan X-Pape Not defining anything
                     turns off this option.

              news_quote_format
                     Format  of  quote  line  when  posting/following  up  an  article   (%A=Address,   %D=Date,
                     %F=Fullname+Address,  %G=Groupname, %M=Message-ID, %N=Fullname, %C=Firstname, %I=Initials).
                     Default is "%F wrote:".

              nntp_read_timeout_secs
                     Time in seconds to wait for a response from the server. Default is 120.

              normalization_form
                     The normalization form which should be used  to  normalize  unicode  input.   The  possible
                     values are:

                        0  None: no normalization

                        1  NFKC: Compatibility Decomposition, followed by Canonical Composition

                        2  NFKD: Compatibility Decomposition

                        3  NFC: Canonical Decomposition, followed by Canonical Composition

                        4  NFD: Canonical Decomposition

                        5  NFKC_CF:  Compatibility  Decomposition,  followed  by  Canonical Composition and Case
                           Folding
              Some normalization modes are only available if they are supported by the library tin(1) uses to do
              the normalization. NFC should be used if possible.

              page_mime_format
                     Format  string  tin(1)  uses  for  mime  header   at   Page   level.    Default   is   "[--
                     %T%S%*n%z%*l%!c%!d%*e --]".

              page_uue_format
                     Format  string  tin(1)  uses for uue header at Page level.  Default is "[-- %T%S%*n%I%!d%*e
                     --]".

              pos_first_unread
                     If ON put cursor at first unread article in group otherwise at last article. Default is ON.

              post_8bit_header
                     Allows 8bit characters unencoded in the header of a news article, if set this also disables
                     the generation of MIME-headers when they are usually required. Default is OFF. Only enacted
                     if post_mime_encoding is also set to 8bit. In a number  of  local  hierarchies  where  8bit
                     characters  are  used,  using  unencoded  (raw) 8bit characters in header is acceptable and
                     sometimes even recommended so that you need to check the convention adopted  in  the  local
                     hierarchy of your interest to determine what to do with this and post_mime_encoding.

              post_mime_encoding
                     MIME  encoding  of the body in news message, if necessary. (8bit, base64, quoted-printable,
                     7bit). Default is 8bit, which leads  to  no  encoding.   base64  and  quoted-printable  are
                     usually undesired on usenet.

              post_process_view
                     If  ON, then tin(1) will start an appropriate viewer program to display any files that were
                     post processed and uudecoded. The program is determined using the mailcap(5) file.  Default
                     is ON.

              post_process_type
                     This  specifies  whether  to  perform post processing on saved articles.  Because the shell
                     archive may contain commands you may not want to be executed, be  careful  when  extracting
                     shell archives.  The following values are allowed:

                        0  No (default), no post processing is done.

                        1  Shell archives, unpacking of multi-part shar(1) files only.

                        2  Yes, binary attachments and data will be decoded and saved.

              posted_articles_file
                     Keep  posted  articles in given file. If the given filename does not contain any expandable
                     strings it will be prefixed with ${TIN_HOMEDIR:-"$HOME"}/Mail/. If no filename is set  then
                     postings  will  not be saved. See the section "MAILING PIPING PRINTING REPOSTING AND SAVING
                     ARTICLES" for more information about the various expansion characters. Default is 'posted'.

              print_header
                     If ON, then the full article header is sent to the printer. Otherwise only the ''Subject:''
                     and ''From:'' fields are output. Default is OFF.

              printer
                     The printer program with options that is to be used  to  print  articles.  The  default  is
                     lpr(1)  for  BSD  machines  and lp(1) for SysV machines. Printing from tin(1) may have been
                     disabled by the System Administrator.

              process_only_unread
                     If ON only save/print/pipe/mail unread articles (tagged  articles  excepted).   Default  is
                     OFF.

              prompt_followupto
                     If ON show empty ''Followup-To:'' header when editing an article.  Default is OFF.

              quote_chars
                     The  character used in quoting included text to article followups and mail replies. The '_'
                     character represents a blank character and is replaced with ' ' when read, %I  is  replaced
                     by author's initials. Default is '>_'.

                     Enable highlighting URLs in message body. Default is ON.

              use_color
                     If enabled tin(1) uses ANSI-colors. Default is OFF.

              use_keypad
                     Use scroll keys on keypad. Default is OFF.

              use_mouse
                     Allows the mouse button support in an xterm(1x) to be enabled/disabled.  Default is OFF.

              use_slrnface
                     If enabled slrnface(1) will be used to interpret the ''X-Face:'' header. For this option to
                     have any effect, tin(1) must be running in an xterm(1x) and slrnface(1)  must  be  in  your
                     $PATH. Default is OFF.

              utf8_graphics
                     If  ON  use  UTF-8  characters  for  indicator  ('->'), thread/attachment tree and ellipsis
                     ('...'). Default is OFF.

              verbatim_begin_regex
                     A regular expression that tin(1) will use to find the begin of a verbatim block. Default is
                     #v+

              verbatim_end_regex
                     A regular expression that tin(1) will use to find the end of a verbatim block.  Default  is

                     #v-
              verbatim_handling
                     If ON verbatim blocks will be detected. Default is ON.

              wildcard
                     Allows  you  to select how tin(1) matches strings. The default is 0 and uses the wildmat(3)
                     notation, which is how this has traditionally been handled.  Setting this to 1  allows  you
                     to use perl(1) compatible regular expressions pcre(3) or pcre2(3).  (see also perlre(1) and
                     pcrepattern(3)  or  pcre2pattern(3)).  You will probably want to update your filter file if
                     you use this regularly.  NB: Newsgroup names will always be matched  using  the  wildmat(3)
                     notation.

              word_h_display_marks
                     Should  the  leading  and ending stars, slashes, strokes and dashes also be displayed, even
                     when they are highlighting marks?

                        0  no

                        1  yes, display mark

                        2  print a space instead

              word_highlight
                     Enable word highlighting. See word_h_display_marks for the options available. If  use_color
                     is   enabled   the  colors  specified  in  col_markdash,  col_markslash,  col_markstar  and
                     col_markstroke are used for word highlighting else the character  attributes  specified  in
                     mono_markdash, mono_markslash, mono_markstar and mono_markstroke are used. Default is ON.

              wrap_column
                     Sets  the  column  at  which  a displayed article body should be wrapped.  If this value is
                     equal to 0, it defaults to the current screen width.  If this value is  greater  than  your
                     current  screen  width  the part off-screen is not displayed. Thus setting this option to a
                     large value can be used to disable wrapping. If this value is negative the wrap  margin  is
                     the  current  screen  width  plus the given value (as long as the result is still positive,
                     otherwise it will fall back to the current screen width). Default is  0,  wrapping  at  the
                     current screen width.

              wrap_on_next_unread
                     If  enabled a search for the next unread article will wrap around all articles to find also
                     previous unread articles. If disabled the search stops at  the  end  of  the  thread  list.
                     Default is ON.

              xpost_quote_format
                     Format  is the same as for news_quote_format, this is used when answering to a crossposting
                     to several groups with no ''Followup-To:'' set.

       /etc/tin/tin.defaults

              Yet another global configuration file with "variable=value"  pairs.  This  one  is  for  the  more
              general  options  which  usually  can't  be  controlled via ${TIN_LIBDIR:-NEWSLIBDIR}/tinrc and/or
              ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc  like  resetting  (to  override  the  built-in   default)   the

                     The  default  points  to  a  developers  mailing list located at tin.org. You might want to
                     change this address to one of your local administration if  you  want  to  deal  with  your
                     lusers problems on your own.

              inewsdir
                     Defines the directory containing the inews(1) executable.

              disable_gnksa_domain_check
                     Allow unregistered top level domains. As the list of  valid  TLDs  is  no  longer  actively
                     maintained the default was changed to ON starting with tin(1) version 2.1.5

              disable_sender
                     Don't  generate  a  ''Sender:''  header.  This  has  an effect only if inews_prog is set to
                     --internal.

              spooldir
                     Base of your newsspool (Bnews, Cnews and INN traditional spool style),  common  values  are

       /usr/local/share/locale/$LC_MESSAGES/LC_MESSAGES/tin.mo

              translation into language specified in $LC_ALL, $LC_MESSAGES or $LANG

       ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active}

              This  file lists the newsgroups that the local site receives. Each newsgroup should be listed only
              once. Each line specifies one group; within each newsgroup, articles are  assigned  unique  names,
              which are monotonically increasing numbers.

              If  an  article  is posted to newsgroups not mentioned in this file, those newsgroups are ignored.
              If no valid newsgroups are specified, the article is rejected.

              Each line consists of four space-separated fields "name highmark lowmark flags".

              name   is the name of the newsgroup

              highmark
                     is the highest article number that has been used in that newsgroup

              lowmark
                     is the lowest article number in the group; this number is not guaranteed  to  be  accurate,
                     and  should  only  be taken to be a hint. Note that because of article cancellations, there
                     may be gaps in the numbering sequence. If the lowest article number  is  greater  than  the
                     highest article number, then there are no articles in the newsgroup.

              flags  can be one of those

                     y      local postings are allowed

                     n      no local postings are allowed, only remote ones

                     m      the group is moderated and all postings must be approved

                     j      articles in this group are not kept, but only passed on

                     x      articles cannot be posted to this newsgroup

                     =foo.bar
                            articles are locally filed into the ''foo.bar'' group

              tin(1) only tries to read the file if you read directly from the local spool, if you read news via
                     NNTP, tin(1) uses the LIST (RFC3977) or LIST COUNTS (RFC6048) command instead.

       ${TIN_LIBDIR:-NEWSLIBDIR}/active.times

              This  file  provides a chronological record of when newsgroups are created. It is normally updated
              by the local news server (e.g.  innd(8)) whenever a new group is created.  Each  line  consist  of
              three space-separated fields "name time creator".

              name   is the name of the newsgroup

              time   is the time when the group was created, expressed as the number of seconds since the Epoch.

              creator
                     is the electronic mail address of the person who created the group.

              tin(1) only tries to read the file if you read directly from the local spool, if you read news via
                     NNTP, tin(1) uses the NEWGROUPS (RFC3977) command instead.

       ${TIN_LIBDIR:-NEWSLIBDIR}/newsgroups

              This  file provides short descriptions of each newsgroup. It is normally updated by the local news
              server (e.g.  innd(8)) whenever a new group is created. Each line  consist  of  two  tab-separated
              fields "group.name          one-line description".

              group.name
                     is the name of the newsgroup

              one-line description
                     is a short single-line description of the group

              tin(1) only tries to read the file if you read directly from the local spool, if you read news via
                     NNTP, tin(1) uses the LIST NEWSGROUPS (RFC3977) command instead.

       ${TIN_LIBDIR:-NEWSLIBDIR}/organization

              This  file  might  hold  a  default  organization  to  be  used  in  the ''Organization:'' header.
              $ORGANIZATION has a higher priority if set.

       ${TIN_LIBDIR:-NEWSLIBDIR}/overview.fmt

              This file specifies the organization of the news overview  database  (see  also  newsoverview(5)).
              The  order  of  lines  in this file is important; it determines the order in which the fields will
              appear in the database. See also overview.fmt(5).  tin(1) only tries to read the file if you  read
              directly  from the local spool, if you read news via NNTP, tin(1) uses the LIST OVERVIEW.FMT (RFC‐
              3977) command instead.

       ${TIN_LIBDIR:-NEWSLIBDIR}/subscriptions

              This file contains a list of newsgroups — one per line — which the client should subscribe to when
              the user has no ${TIN_HOMEDIR:-"$HOME"}/.newsrc for the news server.  tin(1) only  tries  to  read
              the  file  if  you  read directly from the local spool, if you read news via NNTP, tin(1) uses the
              LIST SUBSCRIPTIONS (RFC6048) command instead.
