NAME
gzmore - file perusal filter for crt viewing of compressed text
SYNOPSIS
gzmore
[ name ... ]
DESCRIPTION
Gzmore
is a filter which allows examination of compressed or plain text files
one screenful at a time on a soft-copy terminal.
gzmore
works on files compressed with
compress, pack
or
gzip,
and also on uncompressed files.
If a file does not exist,
gzmore
looks for a file of the same name with the addition of a .gz, .z or .Z suffix.
Gzmore
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.
Gzmore
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
gzmore
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 gzmore to exit.
- s
-
When the prompt --More--(Next file:
file)
is printed, this command causes gzmore 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,
gzmore
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-\).
Gzmore
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
gzmore
acts just like
gzcat,
except that a header is printed before each file.
