6 bzmore, bzless \- file perusal filter for crt viewing of bzip2 compressed text
14 In the following description,
18 can be used interchangeably with
24 is a filter which allows examination of compressed or plain text files
25 one screenful at a time on a soft-copy terminal.
27 works on files compressed with
29 and also on uncompressed files.
30 If a file does not exist,
32 looks for a file of the same name with the addition of a .bz2 suffix.
35 normally pauses after each screenful, printing --More--
36 at the bottom of the screen.
37 If the user then types a carriage return, one more line is displayed.
38 If the user hits a space,
39 another screenful is displayed. Other possibilities are enumerated later.
44 to determine terminal characteristics,
45 and to determine the default window size.
46 On a terminal capable of displaying 24 lines,
47 the default window size is 22 lines.
48 Other sequences which may be typed when
50 pauses, and their effects, are as follows (\fIi\fP is an optional integer
51 argument, defaulting to 1) :
56 more lines, (or another screenful if no argument is given)
59 display 11 more lines (a ``scroll'').
62 is given, then the scroll size is set to \fIi\|\fP.
65 same as ^D (control-D)
68 same as typing a space except that \fIi\|\fP, if present, becomes the new
69 window size. Note that the window size reverts back to the default at the
70 end of the current file.
73 skip \fIi\|\fP lines and print a screenful of lines
76 skip \fIi\fP screenfuls and print a screenful of lines
79 quit reading the current file; go on to the next (if any)
82 When the prompt --More--(Next file:
84 is printed, this command causes bzmore to exit.
87 When the prompt --More--(Next file:
89 is printed, this command causes bzmore to skip the next file and continue.
92 Display the current line number.
95 search for the \fIi\|\fP-th occurrence of the regular expression \fIexpr.\fP
96 If the pattern is not found,
98 goes on to the next file (if any).
99 Otherwise, a screenful is displayed, starting two lines before the place
100 where the expression was found.
101 The user's erase and kill characters may be used to edit the regular
103 Erasing back past the first column cancels the search command.
106 search for the \fIi\|\fP-th occurrence of the last regular expression entered.
109 invoke a shell with \fIcommand\|\fP.
110 The character `!' in "command" are replaced with the
111 previous shell command. The sequence "\\!" is replaced by "!".
114 quit reading the current file; go on to the next (if any)
118 (dot) repeat the previous command.
120 The commands take effect immediately, i.e., it is not necessary to
121 type a carriage return.
122 Up to the time when the command character itself is given,
123 the user may hit the line kill character to cancel the numerical
124 argument being formed.
125 In addition, the user may hit the erase character to redisplay the
128 At any time when output is being sent to the terminal, the user can
129 hit the quit key (normally control\-\\).
131 will stop sending output, and will display the usual --More--
133 The user may then enter one of the above commands in the normal manner.
134 Unfortunately, some output is lost when this is done, due to the
135 fact that any characters waiting in the terminal's output queue
136 are flushed when the quit signal occurs.
138 The terminal is set to
140 mode by this program so that the output can be continuous.
141 What you type will thus not show on your terminal, except for the / and !
144 If the standard output is not a teletype, then
148 except that a header is printed before each file.
