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 displayed.
Other possibilities are enumerated later.
Bzmore looks in the file /etc/termcap to determine termi-
nal characteristics, and to determine the default window
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). Other-
wise, 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-
mand. The sequence "\!" is replaced by "!".
:q or :Q
quit reading the current file; go on to the next
(if any) (same as q or Q).
. (dot) repeat the previous command.
The commands take effect immediately, i.e., it is not nec-
essary to type a carriage return. Up to the time when the
command character itself is given, the user may hit the
line kill character to cancel the numerical argument being
formed. In addition, the user may hit the erase character
to redisplay the --More-- message.
At any time when output is being sent to the terminal, the
user can hit the quit key (normally control-\). 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 char-
acters 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.
