zmore - file perusal filter for crt viewing of compressed
text
SYNOPSIS
zmore [ name ... ]
DESCRIPTION
Zmore is a filter which allows examination of compressed or
plain text files one screenful at a time on a soft-copy
terminal. zmore 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.
Zmore 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.
