.TH ZMORE 1
|
|
.SH NAME
|
|
zmore \- file perusal filter for crt viewing of compressed text
|
|
.SH SYNOPSIS
|
|
.B zmore
|
|
[ name ... ]
|
|
.SH DESCRIPTION
|
|
.I Zmore
|
|
is a filter which allows examination of compressed or plain text files
|
|
one screenful at a time on a soft-copy terminal.
|
|
.I zmore
|
|
works on files compressed with
|
|
.I compress, pack
|
|
or
|
|
.I gzip,
|
|
and also on uncompressed files.
|
|
If a file does not exist,
|
|
.I zmore
|
|
looks for a file of the same name with the addition of a .gz, .z or .Z suffix.
|
|
.PP
|
|
.I 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.
|
|
.PP
|
|
.I Zmore
|
|
looks in the file
|
|
.I /usr/share/misc/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
|
|
.I more,
|
|
set environment variable PAGER to the name of the desired program, such as
|
|
.I less.
|
|
.PP
|
|
Other sequences which may be typed when
|
|
.I zmore
|
|
pauses, and their effects, are as follows (\fIi\fP is an optional integer
|
|
argument, defaulting to 1) :
|
|
.PP
|
|
.IP \fIi\|\fP<space>
|
|
display
|
|
.I i
|
|
more lines, (or another screenful if no argument is given)
|
|
.PP
|
|
.IP ^D
|
|
display 11 more lines (a ``scroll'').
|
|
If
|
|
.I i
|
|
is given, then the scroll size is set to \fIi\|\fP.
|
|
.PP
|
|
.IP d
|
|
same as ^D (control-D)
|
|
.PP
|
|
.IP \fIi\|\fPz
|
|
same as typing a space except that \fIi\|\fP, if present, becomes the new
|
|
window size. Note that the window size reverts back to the default at the
|
|
end of the current file.
|
|
.PP
|
|
.IP \fIi\|\fPs
|
|
skip \fIi\|\fP lines and print a screenful of lines
|
|
.PP
|
|
.IP \fIi\|\fPf
|
|
skip \fIi\fP screenfuls and print a screenful of lines
|
|
.PP
|
|
.IP "q or Q"
|
|
quit reading the current file; go on to the next (if any)
|
|
.PP
|
|
.IP "e or q"
|
|
When the prompt --More--(Next file:
|
|
.IR file )
|
|
is printed, this command causes zmore to exit.
|
|
.PP
|
|
.IP s
|
|
When the prompt --More--(Next file:
|
|
.IR file )
|
|
is printed, this command causes zmore to skip the next file and continue.
|
|
.PP
|
|
.IP =
|
|
Display the current line number.
|
|
.PP
|
|
.IP \fIi\|\fP/expr
|
|
search for the \fIi\|\fP-th occurrence of the regular expression \fIexpr.\fP
|
|
If the pattern is not found,
|
|
.I 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.
|
|
.PP
|
|
.IP \fIi\|\fPn
|
|
search for the \fIi\|\fP-th occurrence of the last regular expression entered.
|
|
.PP
|
|
.IP !command
|
|
invoke a shell with \fIcommand\|\fP.
|
|
The character `!' in "command" are replaced with the
|
|
previous shell command. The sequence "\\!" is replaced by "!".
|
|
.PP
|
|
.IP ":q or :Q"
|
|
quit reading the current file; go on to the next (if any)
|
|
(same as q or Q).
|
|
.PP
|
|
.IP .
|
|
(dot) repeat the previous command.
|
|
.PP
|
|
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.
|
|
.PP
|
|
At any time when output is being sent to the terminal, the user can
|
|
hit the quit key (normally control\-\\).
|
|
.I 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.
|
|
.PP
|
|
The terminal is set to
|
|
.I 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.
|
|
.PP
|
|
If the standard output is not a teletype, then
|
|
.I zmore
|
|
acts just like
|
|
.I zcat,
|
|
except that a header is printed before each file.
