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.
