NAME
zmore - file perusal filter for crt viewing of compressed text
SYNOPSIS
zmore [ name ... ]
DESCRIPTION
The zmore command is a filter which allows examination of compressed or
plain text files one screenful at a time on a soft-copy terminal. The
zmore command 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 suf-
fix.
The zmore command normally pauses after each screenful, printing
--More-- at the bottom of the screen. If the user then types a car-
riage return, one more line is displayed. If the user hits a space,
another screenful is displayed. Other possibilities are enumerated
later.
The zmore command looks in the file /etc/termcap to determine terminal
characteristics, and to determine the default window size. On a termi-
nal 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 ef-
fects, 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.
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
entered.
!command
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-\). The zmore command 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 charac-
ters 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.
