2: .SH NAME
3: zmore \- file perusal filter for crt viewing of compressed text
4: .SH SYNOPSIS
5: .B zmore
6: [ name ... ]
7: .SH DESCRIPTION
8: .I Zmore
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.
16: .PP
17: .I Zmore
18: looks in the file
19: .I /etc/termcap
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.
24: .PP
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>
31: display
32: .I i
33: more lines, (or another screenful if no argument is given)
34: .PP
35: .IP ^D
36: display 11 more lines (a ``scroll'').
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
49: .IP \fIi\|\fPs
50: skip \fIi\|\fP lines and print a screenful of lines
51: .PP
52: .IP \fIi\|\fPf
53: skip \fIi\fP screenfuls and print a screenful of lines
54: .PP
55: .IP "q or Q"
56: quit reading the current file; go on to the next (if any)
57: .PP
58: .IP e
59: When the prompt --More--(Next file:
60: .IR file )
61: is printed, this command causes zmore to exit.
62: .PP
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.
79: .PP
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.
