NAME
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" is 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.
