bmore - browse through a binary file
bmore [ -acdi ] [ -n lines ] [ -w cols ] [ +linenumber ] [ +/ASCII-
pattern ] [ +\Hex-pattern ] [ filename ... ]
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.
-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
-d Display error messages rather than ringing the terminal bell if
an unrecognized command is used. This is helpful for
-i Ignore case for searching.
Displays the indicated number of lines in each screenful, rather
than the default (the number of lines in the terminal screen
Display number of cols in each line.
Start up at linenumber.
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.
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 Exit from more.
= Display the current line number.
v Drop into the bvi(1) editor at the current offset of the
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 Exit from bmore (same as q or Q ).
. Dot. Repeat the previous command.
