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 suffix.

The zmore command 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.

The zmore command looks in the file /etc/termcap to determine
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 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) :

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 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-\). 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 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.
