zmore, zless -- view compressed files
zmore [flags] [file ...]
zless [flags] [file ...]
zmore is a filter that allows the viewing of files compressed with Lem-
pel-Ziv encoding. Such files generally have a ``Z'' or ``gz'' extension
(both the compress(1) and gzip(1) formats are supported). Any flags that
are specified are passed to the user's preferred PAGER (which is
/usr/bin/more by default).
zless is equivalent to zmore but uses less(1) as a pager instead of
When multiple files are specified, zmore will pause at the end of each
file and present the following prompt to the user:
prev_file (END) - Next: next_file
Where prev_file is the file that was just displayed and next_file is the
next file to be displayed. The following keys are recognized at the
e or q quit zmore.
s skip the next file (or exit if the next file is the last).
If no files are specified, zmore will read from the standard input. In
this mode zmore will assume gzip(1) style compression since there is no
suffix on which to make a decision.
PAGER Program used to display files. If unset, /usr/bin/more is used
(zmore) or /usr/bin/less (zless).

zmore - file perusal filter for crt viewing of compressed text
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 /etc/termcap to determine terminal characteris-
tics, 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 variable PAGER to
the name of the desired program, such as less.
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
^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.
is skip i lines and print a screenful of lines
if skip i screenfuls and print a screenful of lines
q or Q Quit.
= Display the current line number.
i/expr search for the i-th occurrence of the regular expression expr.
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
invoke a shell with command. The character `!' in "command" is
replaced with the previous shell command. The sequence "\!" is
replaced by "!".
:q or :Q
Quit (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 charac-
ter 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 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 zmore acts just like
zcat, except that a header is printed before each file if there is more
than one file.
