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.
