5 zmore \- file perusal filter for crt viewing of compressed text
11 is a filter which allows examination of compressed or plain text files
12 one screenful at a time on a soft-copy terminal.
14 works on files compressed with
18 and also on uncompressed files.
19 If a file does not exist,
21 looks for a file of the same name with the addition of a .gz, .z or .Z suffix.
24 normally pauses after each screenful, printing --More--
25 at the bottom of the screen.
26 If the user then types a carriage return, one more line is displayed.
27 If the user hits a space,
28 another screenful is displayed. Other possibilities are enumerated later.

33 to determine terminal characteristics,
34 and to determine the default window size.
35 On a terminal capable of displaying 24 lines,
36 the default window size is 22 lines.
37 To use a pager other than the default
39 set environment variable PAGER to the name of the desired program, such as
42 Other sequences which may be typed when
44 pauses, and their effects, are as follows (\fIi\fP is an optional integer
45 argument, defaulting to 1) :
50 more lines, (or another screenful if no argument is given)
53 display 11 more lines (a ``scroll'').
56 is given, then the scroll size is set to \fIi\|\fP.
59 same as ^D (control-D)
62 same as typing a space except that \fIi\|\fP, if present, becomes the new
63 window size. Note that the window size reverts back to the default at the
64 end of the current file.
67 skip \fIi\|\fP lines and print a screenful of lines
70 skip \fIi\fP screenfuls and print a screenful of lines
73 quit reading the current file; go on to the next (if any)
76 When the prompt --More--(Next file:
78 is printed, this command causes zmore to exit.
81 When the prompt --More--(Next file:
83 is printed, this command causes zmore to skip the next file and continue.
86 Display the current line number.
89 search for the \fIi\|\fP-th occurrence of the regular expression \fIexpr.\fP
90 If the pattern is not found,
92 goes on to the next file (if any).
93 Otherwise, a screenful is displayed, starting two lines before the place
94 where the expression was found.
95 The user's erase and kill characters may be used to edit the regular
97 Erasing back past the first column cancels the search command.
100 search for the \fIi\|\fP-th occurrence of the last regular expression entered.
103 invoke a shell with \fIcommand\|\fP.
104 The character `!' in "command" are replaced with the
105 previous shell command. The sequence "\\!" is replaced by "!".
108 quit reading the current file; go on to the next (if any)
112 (dot) repeat the previous command.
114 The commands take effect immediately, i.e., it is not necessary to
115 type a carriage return.
116 Up to the time when the command character itself is given,
117 the user may hit the line kill character to cancel the numerical
118 argument being formed.
119 In addition, the user may hit the erase character to redisplay the
122 At any time when output is being sent to the terminal, the user can
123 hit the quit key (normally control\-\\).
125 will stop sending output, and will display the usual --More--
127 The user may then enter one of the above commands in the normal manner.
128 Unfortunately, some output is lost when this is done, due to the
129 fact that any characters waiting in the terminal's output queue
130 are flushed when the quit signal occurs.
132 The terminal is set to
134 mode by this program so that the output can be continuous.
135 What you type will thus not show on your terminal, except for the / and !
138 If the standard output is not a teletype, then
142 except that a header is printed before each file.
