NAME
bzmore, bzless - file perusal filter for crt viewing of bzip2 com-
pressed text
SYNOPSIS
bzmore [ name ... ]
bzless [ name ... ]
NOTE
In the following description, bzless and less can be used interchange-
ably 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 terminal character-
istics, and to determine the default window size. On a terminal capa-
ble 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
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 com-
mand causes bzmore to exit.
s When the prompt --More--(Next file: file) is printed, this com-
mand 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 regu-
lar 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 command. 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 necessary 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 out-
put, 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.
