PROGRAM:

NAME

bmore - browse through a binary file

SYNOPSIS

bmore [ -acdi ] [ -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).

-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.
