NAME
gzmore - file perusal filter for crt viewing of compressed text
SYNOPSIS
gzmore [ name ... ]
DESCRIPTION
Gzmore is a filter which allows examination of compressed or plain text
files one screenful at a time on a soft-copy terminal. gzmore works on
files compressed with compress, pack or gzip, and also on uncompressed
files. If a file does not exist, gzmore looks for a file of the same
name with the addition of a .gz, .z or .Z suffix.
Gzmore 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.
Gzmore 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. 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 gzmore pauses, and their
effects, 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-\). Gzmore 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 gzmore acts just like
gzcat, except that a header is printed before each file if there is
more than one file.
