NAME
bzmore, bzless - file perusal filter for crt viewing of bzip2 compressed text
SYNOPSIS
bzmore [ name ... ]
bzless [ name ... ]
NOTE
In the following description, bzless and less can be used interchangeably with bzmore and more.
DESCRIPTION
Bzmore is a filter which allows examination of compressed or plain text files one screenful at a time on a
soft-copy terminal. bzmore works on files compressed with bzip2 and also on uncompressed files. If a file
does not exist, bzmore looks for a file of the same name with the addition of a .bz2 suffix.
Bzmore normally pauses after each screenful, printing --More-- at the bottom of the screen. If the user then
types a carriage return, one more line is displayed. If the user hits a space, another screenful is dis‐
played. Other possibilities are enumerated later.
Bzmore looks in the file /etc/termcap to determine terminal characteristics, and to determine the default win‐
dow size. On a terminal capable of displaying 24 lines, the default window size is 22 lines. Other sequences
which may be typed when bzmore pauses, and their effects, are as follows (i is an optional integer argument,
defaulting to 1) :
i<space>
display i more lines, (or another screenful if no argument is given)
^D display 11 more lines (a ``scroll''). If i is given, then the scroll size is set to i.
d same as ^D (control-D)
iz same as typing a space except that i, if present, becomes the new window size. Note that the window
size reverts back to the default at the end of the current file.
is skip i lines and print a screenful of lines
if skip i screenfuls and print a screenful of lines
q or Q quit reading the current file; go on to the next (if any)
e or q When the prompt --More--(Next file: file) is printed, this command causes bzmore to exit.
s When the prompt --More--(Next file: file) is printed, this command causes bzmore to skip the next file
and continue.
= Display the current line number.
i/expr search for the i-th occurrence of the regular expression expr. If the pattern is not found, bzmore
goes on to the next file (if any). Otherwise, a screenful is displayed, starting two lines before the
place where the expression was found. The user's erase and kill characters may be used to edit the
regular expression. Erasing back past the first column cancels the search command.
in search for the i-th occurrence of the last regular expression entered.
!command
invoke a shell with command. The character `!' in "command" are replaced with the previous shell com‐
Bzmore will stop sending output, and will display the usual --More-- prompt. The user may then enter one of
the above commands in the normal manner. Unfortunately, some output is lost when this is done, due to the
fact that any characters waiting in the terminal's output queue are flushed when the quit signal occurs.
The terminal is set to noecho mode by this program so that the output can be continuous. What you type will
thus not show on your terminal, except for the / and ! commands.
If the standard output is not a teletype, then bzmore acts just like bzcat, except that a header is printed
before each file.
