ZMORE(1)ZMORE(1)NAMEzmore - file perusal filter for crt viewing of compressed text
SYNOPSISzmore [ 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. 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 zmore to exit.
s When the prompt --More--(Next file: file) is printed, this com‐
mand 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). 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
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 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 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.
