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.
