3 zmore \- file perusal filter for crt viewing of compressed text
9 is a filter which allows examination of compressed or plain text files
10 one screenful at a time on a soft-copy terminal.
12 works on files compressed with
16 and also on uncompressed files.
17 If a file does not exist,
19 looks for a file of the same name with the addition of a .gz, .z or .Z suffix.
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.
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
37 Other sequences which may be typed when
39 pauses, and their effects, are as follows (\fIi\fP is an optional integer
40 argument, defaulting to 1) :
45 more lines, (or another screenful if no argument is given)
48 display 11 more lines (a ``scroll'').
51 is given, then the scroll size is set to \fIi\fP.
54 same as ^D (control-D)
57 same as typing a space except that \fIi\fP, if present, becomes the new
58 window size. Note that the window size reverts back to the default at the
59 end of the current file.
62 skip \fIi\fP lines and print a screenful of lines
65 skip \fIi\fP screenfuls and print a screenful of lines
68 quit reading the current file; go on to the next (if any)
71 When the prompt --More--(Next file:
73 is printed, this command causes zmore to exit.
76 When the prompt --More--(Next file:
78 is printed, this command causes zmore to skip the next file and continue.
81 Display the current line number.
84 search for the \fIi\^\fP-th occurrence of the regular expression \fIexpr.\fP
85 If the pattern is not found,
87 goes on to the next file (if any).
88 Otherwise, a screenful is displayed, starting two lines before the place
89 where the expression was found.
90 The user's erase and kill characters may be used to edit the regular
92 Erasing back past the first column cancels the search command.
95 search for the \fIi\^\fP-th occurrence of the last regular expression entered.
98 invoke a shell with \fIcommand\fP.
99 The character `!' in "command" is replaced with the
100 previous shell command. The sequence "\\!" is replaced by "!".
103 quit reading the current file; go on to the next (if any)
107 (dot) repeat the previous command.
109 The commands take effect immediately, i.e., it is not necessary to
110 type a carriage return.
111 Up to the time when the command character itself is given,
112 the user may hit the line kill character to cancel the numerical
113 argument being formed.
114 In addition, the user may hit the erase character to redisplay the
117 At any time when output is being sent to the terminal, the user can
118 hit the quit key (normally control\-\\).
120 will stop sending output, and will display the usual --More--
122 The user may then enter one of the above commands in the normal manner.
123 Unfortunately, some output is lost when this is done, due to the
124 fact that any characters waiting in the terminal's output queue
125 are flushed when the quit signal occurs.
127 The terminal is set to
129 mode by this program so that the output can be continuous.
130 What you type will thus not show on your terminal, except for the / and !
133 If the standard output is not a teletype, then
137 except that a header is printed before each file.
