zmore - file perusal filter for crt viewing of compressed
zmore [ name ... ]
Zmore is a filter which allows examination of compressed
or plain text files one screenful at a time on a soft-copy
terminal. zmore works on files compressed with compress,
pack or gzip, and also on uncompressed files. If a file
does not exist, zmore looks for a file of the same name
with the addition of a .gz, .z or .Z suffix.
Zmore 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.
Zmore looks in the file /usr/share/misc/termcap to deter-
mine terminal characteristics, and to determine the
default window size. On a terminal capable of displaying
24 lines, the default window size is 22 lines. To use a
pager other than the default more, set environment vari-
able PAGER to the name of the desired program, such as
Other sequences which may be typed when zmore pauses, and
their effects, are as follows (i is an optional integer
argument, defaulting to 1) :
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
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
e or q When the prompt --More--(Next file: file) is
printed, this command causes zmore to exit.
s When the prompt --More--(Next file: file) is
printed, this command causes zmore 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,
zmore 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
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-\). Zmore
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 zmore acts
just like zcat, except that a header is printed before
