9 is a filter which allows examination of compressed text files
|
|
|
10 one screenful at a time on a soft-copy terminal.
|
|
|
11 It normally pauses after each screenful, printing --More--
|
|
|
12 at the bottom of the screen.
|
|
|
13 If the user then types a carriage return, one more line is displayed.
|
|
|
14 If the user hits a space,
|
|
|
15 another screenful is displayed. Other possibilites are enumerated later.

20 to determine terminal characteristics,
|
|
|
21 and to determine the default window size.
|
|
|
22 On a terminal capable of displaying 24 lines,
|
|
|
23 the default window size is 22 lines.

25 Other sequences which may be typed when
|
|
|
26 .I zmore
|
|
|
27 pauses, and their effects, are as follows (\fIi\fP is an optional integer
|
|
|
28 argument, defaulting to 1) :
|
|

29 .PP
|

30 .IP \fIi\|\fP<space>

|
|
|
37 If
|
|
|
38 .I i
|
|
|
39 is given, then the scroll size is set to \fIi\|\fP.
|
|
|
40 .PP
|
|

41 .IP d

42 same as ^D (control-D)
|
|
|
43 .PP
|
|
|
44 .IP \fIi\|\fPz
|
|
|
45 same as typing a space except that \fIi\|\fP, if present, becomes the new
|
|
|
46 window size. Note that the window size reverts back to the default at the
|
|
|
47 end of the current file.
|

48 .PP

58 .IP e
|
|
|
59 When the prompt --More--(Next file:
|
|
|
60 .IR file )
|
|
|
61 is printed, this command causes zmore to exit.

63 .IP =

64 Display the current line number.
|

65 .PP
|
|
|
66 .IP \fIi\|\fP/expr
|
|
|
67 search for the \fIi\|\fP-th occurrence of the regular expression \fIexpr.\fP
|
|
|
68 If the pattern is not found,
|
|
|
69 .I zmore
|
|
|
70 goes on to the next file (if any).
|
|
|
71 Otherwise, a screenful is displayed, starting two lines before the place
|
|
|
72 where the expression was found.
|
|
|
73 The user's erase and kill characters may be used to edit the regular
|
|
|
74 expression.
|
|
|
75 Erasing back past the first column cancels the search command.
|
|
|
76 .PP
|
|
|
77 .IP \fIi\|\fPn
|
|
|
78 search for the \fIi\|\fP-th occurrence of the last regular expression entered.

|
|
|
80 .IP !command
|
|
|
81 invoke a shell with \fIcommand\|\fP.
|
|
|
82 The character `!' in "command" are replaced with the
|
|
|
83 the previous shell command. The sequence "\\!" is replaced by "!".
|

|
84 .PP
|
|
|
85 .IP ":q or :Q"
|
|
|
86 quit reading the current file; go on to the next (if any)
|
|
|
87 (same as q or Q).

88 .PP
|

89 .IP .
|
|

90 (dot) repeat the previous command.
|
|
|
91 .PP
|
|
|
92 The commands take effect immediately, i.e., it is not necessary to
|
|
|
93 type a carriage return.
|
|
|
94 Up to the time when the command character itself is given,
|
|
|
95 the user may hit the line kill character to cancel the numerical
|
|
|
96 argument being formed.
|
|
|
97 In addition, the user may hit the erase character to redisplay the
|
|
|
98 --More-- message.
|
|
|
99 .PP
|
|
|
100 At any time when output is being sent to the terminal, the user can
|
|
|
101 hit the quit key (normally control\-\\).
|
|
|
102 .I Zmore
|
|
|
103 will stop sending output, and will display the usual --More--
|
|
|
104 prompt.
|
|
|
105 The user may then enter one of the above commands in the normal manner.
|
|
|
106 Unfortunately, some output is lost when this is done, due to the
|
|
|
107 fact that any characters waiting in the terminal's output queue
|
|
|
108 are flushed when the quit signal occurs.
|
|
|
109 .PP
|
|
|
110 The terminal is set to
|
|
|
111 .I noecho
|
|
|
112 mode by this program so that the output can be continuous.
|
|
|
113 What you type will thus not show on your terminal, except for the / and !
|
|
|
114 commands.
|
|
|
115 .PP
|
|
|
116 If the standard output is not a teletype, then
|
|
|
117 .I zmore
|
|
|
118 acts just like
|
|
|
119 .I zcat,
|
|
|
120 except that a header is printed before each file.
