NAME

       mu-view - display an e-mail message file

SYNOPSIS

       mu [COMMON OPTIONS] view [OPTIONS] [FILE...]

DESCRIPTION

       mu  view  is  the  mu command for displaying e-mail message files. It works on message files and does not
       require the message to be indexed in the database.

       The command shows some common  headers  (From:,  To:,  Cc:,  Bcc:,  Subject:  and  Date:),  the  list  of
       attachments  and  either  the  plain-text  or  html  body  of  the  message (if any), or its s-expression
       representation.

       If no message file is provided, the command reads the message from standard-input.

VIEW OPTIONS

   -o, --format format
       Use the given output format, one of:

       —   plain: use the plain-text body; this is the default,

       —   html: use the HTML body,

       —   sexp: show the S-expression representation of the message.

   --summary-len number
       Instead of displaying the full message, output a summary  based  upon  the  first  number  lines  of  the
       message.

   --terminate
       Terminate  messages  with \f (form-feed) characters when displaying them. This is useful when you want to
       further process them.

   --decrypt
       Attempt to decrypt encrypted message bodies. This is only possible if mu was built with crypto-support.

   --auto-retrieve
       Attempt to retrieve crypto-keys automatically from the network, when needed.

COMMON OPTIONS

   -d, --debug
       Makes mu generate extra debug information, useful for debugging the  program  itself.  Debug  information
       goes to the standard logging location; see mu(1).

   -q, --quiet
       Causes  mu  not to output informational messages and progress information to standard output, but only to
       the log file. Error messages will still be sent to standard error. Note that mu index is much faster with
       --quiet, so it is recommended you use this option when using mu from scripts etc.

   --log-stderr
       Causes mu to not output log messages to standard error, in addition  to  sending  them  to  the  standard
       logging location.

   --nocolor
       Do not use ANSI colors. The environment variable NO_COLOR can be used as an alternative to --nocolor.

   -V, --version
       Prints mu version and copyright information.

   -h, --help
       Lists the various command line options.
