|
|---|
| 7 | .SH DESCRIPTION
|
|---|
| 8 | .I Zmore
|
|---|
| 9 | is a filter which allows examination of compressed or plain text files
|
|---|
| 10 | one screenful at a time on a soft-copy terminal.
|
|---|
| 11 | .I zmore
|
|---|
| 12 | works on files compressed with
|
|---|
| 13 | .I compress, pack
|
|---|
| 14 | or
|
|---|
| 15 | .I gzip,
|
|---|
| 16 | and also on uncompressed files.
|
|---|
| 17 | If a file does not exist,
|
|---|
| 18 | .I zmore
|
|---|
| 19 | looks for a file of the same name with the addition of a .gz, .z or .Z suffix.
|
|---|
| 20 | .PP
|
|---|
| 21 | .I Zmore
|
|---|
| 22 | normally pauses after each screenful, printing --More--
|
|---|
| 23 | at the bottom of the screen.
|
|---|
| 24 | If the user then types a carriage return, one more line is displayed.
|
|---|
| 25 | If the user hits a space,
|
|---|
| 26 | another screenful is displayed. Other possibilities are enumerated later.
|
|---|
| 27 | .PP
|
|---|
| 28 | .I Zmore
|
|---|
| 29 | looks in the file
|
|---|
| 30 | .I /etc/termcap
|
|---|
| 31 | to determine terminal characteristics,
|
|---|
| 32 | and to determine the default window size.
|
|---|
| 33 | On a terminal capable of displaying 24 lines,
|
|---|
| 34 | the default window size is 22 lines.
|
|---|
| 35 | To use a pager other than the default
|
|---|
| 36 | .I more,
|
|---|
| 37 | set environment variable PAGER to the name of the desired program, such as
|
|---|
| 38 | .I less.
|
|---|
| 39 | .PP
|
|---|
| 40 | Other sequences which may be typed when
|
|---|
| 41 | .I zmore
|
|---|
| 42 | pauses, and their effects, are as follows (\fIi\fP is an optional integer
|
|---|
| 43 | argument, defaulting to 1) :
|
|---|
| 44 | .PP
|
|---|
| 45 | .IP \fIi\^\fP<space>
|
|---|
| 46 | display
|
|---|
| 47 | .I i
|
|---|
| 48 | more lines, (or another screenful if no argument is given)
|
|---|
| 49 | .PP
|
|---|
| 50 | .IP ^D
|
|---|
| 51 | display 11 more lines (a ``scroll'').
|
|---|
| 52 | If
|
|---|
| 53 | .I i
|
|---|
| 54 | is given, then the scroll size is set to \fIi\fP.
|
|---|
| 55 | .PP
|
|---|
| 56 | .IP d
|
|---|
| 57 | same as ^D (control-D)
|
|---|
| 58 | .PP
|
|---|
| 59 | .IP \fIi\^\fPz
|
|---|
| 60 | same as typing a space except that \fIi\fP, if present, becomes the new
|
|---|
| 61 | window size. Note that the window size reverts back to the default at the
|
|---|
| 62 | end of the current file.
|
|---|
| 63 | .PP
|
|---|
| 64 | .IP \fIi\^\fPs
|
|---|
| 65 | skip \fIi\fP lines and print a screenful of lines
|
|---|
| 66 | .PP
|
|---|
| 67 | .IP \fIi\^\fPf
|
|---|
| 68 | skip \fIi\fP screenfuls and print a screenful of lines
|
|---|
| 69 | .PP
|
|---|
| 70 | .IP "q or Q"
|
|---|
| 71 | quit reading the current file; go on to the next (if any)
|
|---|
| 72 | .PP
|
|---|
| 73 | .IP "e or q"
|
|---|
| 74 | When the prompt --More--(Next file:
|
|---|
| 75 | .IR file )
|
|---|
| 76 | is printed, this command causes zmore to exit.
|
|---|
| 77 | .PP
|
|---|
| 78 | .IP s
|
|---|
| 79 | When the prompt --More--(Next file:
|
|---|
| 80 | .IR file )
|
|---|
| 81 | is printed, this command causes zmore to skip the next file and continue.
|

| 83 | .IP =
|
|---|
| 84 | Display the current line number.
|
|---|
| 85 | .PP
|
|---|
| 86 | .IP \fIi\fP/expr
|
|---|
| 87 | search for the \fIi\^\fP-th occurrence of the regular expression \fIexpr.\fP
|
|---|
| 88 | If the pattern is not found,
|
|---|
| 89 | .I zmore
|
|---|
| 90 | goes on to the next file (if any).
|
|---|
| 91 | Otherwise, a screenful is displayed, starting two lines before the place
|
|---|
| 92 | where the expression was found.
|
|---|
| 93 | The user's erase and kill characters may be used to edit the regular
|
|---|
| 94 | expression.
|
|---|
| 95 | Erasing back past the first column cancels the search command.
|
|---|
| 96 | .PP
|
|---|
| 97 | .IP \fIi\^\fPn
|
|---|
| 98 | search for the \fIi\^\fP-th occurrence of the last regular expression entered.
|
|---|
| 99 | .PP
|
|---|
| 100 | .IP !command
|
|---|
| 101 | invoke a shell with \fIcommand\fP.
|
|---|
| 102 | The character `!' in "command" is replaced with the
|
|---|
| 103 | previous shell command. The sequence "\\!" is replaced by "!".
|
|---|
| 104 | .PP
|
|---|
| 105 | .IP ":q or :Q"
|
|---|
| 106 | quit reading the current file; go on to the next (if any)
|
|---|
| 107 | (same as q or Q).
|
|---|
| 108 | .PP
|
|---|
| 109 | .IP .
|
|---|
| 110 | (dot) repeat the previous command.
|
|---|
| 111 | .PP
|
|---|
| 112 | The commands take effect immediately, i.e., it is not necessary to
|
|---|
| 113 | type a carriage return.
|
|---|
| 114 | Up to the time when the command character itself is given,
|
|---|
| 115 | the user may hit the line kill character to cancel the numerical
|
|---|
| 116 | argument being formed.
|
|---|
| 117 | In addition, the user may hit the erase character to redisplay the
|
|---|
| 118 | --More-- message.
|
|---|
| 119 | .PP
|
|---|
| 120 | At any time when output is being sent to the terminal, the user can
|
|---|
| 121 | hit the quit key (normally control\-\\).
|
|---|
| 122 | .I Zmore
|
|---|
| 123 | will stop sending output, and will display the usual --More--
|
|---|
| 124 | prompt.
|
|---|
| 125 | The user may then enter one of the above commands in the normal manner.
|
|---|
| 126 | Unfortunately, some output is lost when this is done, due to the
|
|---|
| 127 | fact that any characters waiting in the terminal's output queue
|
|---|
| 128 | are flushed when the quit signal occurs.
|
|---|
| 129 | .PP
|
|---|
| 130 | The terminal is set to
|
|---|
| 131 | .I noecho
|
|---|
| 132 | mode by this program so that the output can be continuous.
|
|---|
| 133 | What you type will thus not show on your terminal, except for the / and !
|
|---|
| 134 | commands.
|
|---|
| 135 | .PP
|
|---|
| 136 | If the standard output is not a teletype, then
|
|---|
| 137 | .I zmore
|
|---|
| 138 | acts just like
|
|---|
| 139 | .I zcat,
|
|---|
| 140 | except that a header is printed before each file.
