zmore
[ name ... ]
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.
