NAME
zmore - file perusal filter for crt viewing of compressed text

SYNOPSIS
zmore [ name ... ]

DESCRIPTION
Zmore is a filter which allows examination of compressed text files
one screenful at a time on a soft-copy terminal. It 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
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. 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
command causes zmore to exit.

s When the prompt --More--(Next file: file) is printed, this
command 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 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"
are 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 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-. 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.
