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).
|
i
SPACE |
|
Display another screenful, or
i more lines if i is specified. |
|
i RETURN |
|
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. |
