Ubuntu Manpage: bmore - browse through a binary file

NAME

       bmore - browse through a binary file

SYNOPSIS

       bmore  [  -acdir  ]  [  -n  lines  ]  [ -w cols ] [ +linenumber ] [ +/ASCII-pattern ] [ +\Hex-pattern ] [
       filename ... ]

DESCRIPTION

       more is a filter that displays the contents of a binary file on the terminal, one screenful  at  a  time.
       It normally pauses after each screenful, and prints --More-- at the bottom of the screen.  bmore provides
       a  two-line  overlap between screens for continuity.  If bmore is reading from a file rather than a pipe,
       the percentage of characters displayed so far is also shown.

       bmore scrolls up to display one more screen line in response to a RETURN character; it  displays  another
       screenful in response to a SPACE character.  Other commands are listed below.

       The  screen is divided in three sections or panes: The byte offset (extreme left), the hex pane (middle),
       and an ascii pane (right) which shows as printable characters those bytes in the  hex  pane.   On  an  80
       column  terminal  there will be sixteen hex values and their ASCII values on each screen line.  Note that
       (as one would expect) the first byte has the offset '0' (zero).

       bmore sets the terminal to noecho mode, so that the output can be continuous.  Commands that you type  do
       not normally show up on your terminal, except for the / , \ and !  commands.

       If  the  standard  output is not a terminal, more acts just like cat(1V), except that a header is printed
       before each file in a series.

OPTIONS

       -a     ASCII mode: no hex representation of the contents. Non printable characters are displayed as a dot
              (.)

       -c     Clear before displaying. Redrawing the screen instead of scrolling.

       -d     Display error messages rather than ringing the terminal bell if an unrecognized command  is  used.
              This is helpful for inexperienced users.

       -i     Ignore case for searching.

       -n lines
              Displays  the  indicated number of lines in each screenful, rather than the default (the number of
              lines in the terminal screen less two).

       -r     Characters between 160 - 254 are displayed as "reverse video text" as used in some legacy  systems
              (Atari, Commodore, Apple II, etc).

       -w cols
              Display number of cols in each line.

       +linenumber
              Start up at linenumber.

       +/ASCII-pattern
              Start  up  at  the  line  containing  the  regular expression pattern.  Note: unlike editors, this
              construct should not end with a `/'.  If it does, then the trailing slash is taken as a  character
              in the search pattern.

USAGE

Commands
The commands take effect immediately; it is not necessary to type a carriage return. Up to the time
when the command character itself is given, the user may type the line kill character to cancel the
numerical argument being formed. In addition, the user may type the erase character to redisplay the
`--More--(xx%)' message.

In the following commands, i is a numerical argument (1 by default).

iSPACE Display another screenful, or i more lines if i is specified.

iRETURN Display another line, or i more lines, if specified.

i^D (CTRL-D) Display (scroll down) 11 more lines. i is given, the scroll size is set to i.

id Same as ^D.

iz Same as SPACE, except that i, if present, becomes the new default number of lines per
screenful.

is Skip i lines and then print a screenful.

if Skip i screenfuls and then print a screenful.

i^B (CTRL-B) Skip back i screenfuls and then print a screenful.

b Same as ^B (CTRL-D).

q
Q Exit from more.

= Display the current line number.

v Drop into the bvi(1) editor at the current offset of the current file.

w Drop into the bvi(1) editor at the current offset of the current file. Only the portion of the
file displayed on the screen will be loaded.

h Help. Give a description of all the more commands.

i/pattern Search for the ith occurrence of the regular expression pattern. Display the screenful
starting at the file position that contains the ith match for the regular expression ASCII-
pattern, or the end of a pipe, whichever comes first. If bmore is displaying a file and there
is no such match, its position in the file remains unchanged. Regular expressions can be
edited using erase and kill characters. Erasing back past the first column cancels the search
command.

' Single quote. Go to the point from which the last search started. If no search has been
performed in the current file, go to the beginning of the file.

!command Invoke a shell to execute command. The characters % and !, when used within command are
replaced with the current filename and the previous shell command, respectively. If there is
no current filename, % is not expanded. Prepend a backslash to these characters to escape
expansion.

i:n Skip to the ith next filename given in the command line, or to the last filename in the list if
i is out of range.

i:p Skip to the ith previous filename given in the command line, or to the first filename if i is
out of range. If given while more is positioned within a file, go to the beginning of the
file. If more is reading from a pipe, more simply rings the terminal bell.

:f Display the current filename and offset number.

:q
:Q Exit from bmore (same as q or Q ).

. Dot. Repeat the previous command.
