bzmore, bzless \- file perusal filter for crt viewing of bzip2 compressed text
13
In the following description,
17
can be used interchangeably with
23
is a filter which allows examination of compressed or plain text files
24
one screenful at a time on a soft-copy terminal.
26
works on files compressed with
28
and also on uncompressed files.
29
If a file does not exist,
31
looks for a file of the same name with the addition of a .bz2 suffix.
34
normally pauses after each screenful, printing --More--
35
at the bottom of the screen.
36
If the user then types a carriage return, one more line is displayed.
37
If the user hits a space,
38
another screenful is displayed. Other possibilities are enumerated later.
43
to determine terminal characteristics,
44
and to determine the default window size.
45
On a terminal capable of displaying 24 lines,
46
the default window size is 22 lines.
47
Other sequences which may be typed when
49
pauses, and their effects, are as follows (\fIi\fP is an optional integer
50
argument, defaulting to 1) :
55
more lines, (or another screenful if no argument is given)
58
display 11 more lines (a ``scroll'').
61
is given, then the scroll size is set to \fIi\|\fP.
64
same as ^D (control-D)
67
same as typing a space except that \fIi\|\fP, if present, becomes the new
68
window size. Note that the window size reverts back to the default at the
69
end of the current file.
72
skip \fIi\|\fP lines and print a screenful of lines
75
skip \fIi\fP screenfuls and print a screenful of lines
78
quit reading the current file; go on to the next (if any)
81
When the prompt --More--(Next file:
83
is printed, this command causes bzmore to exit.
86
When the prompt --More--(Next file:
88
is printed, this command causes bzmore to skip the next file and continue.
91
Display the current line number.
94
search for the \fIi\|\fP-th occurrence of the regular expression \fIexpr.\fP
95
If the pattern is not found,
97
goes on to the next file (if any).
98
Otherwise, a screenful is displayed, starting two lines before the place
99
where the expression was found.
100
The user's erase and kill characters may be used to edit the regular
102
Erasing back past the first column cancels the search command.
105
search for the \fIi\|\fP-th occurrence of the last regular expression entered.
108
invoke a shell with \fIcommand\|\fP.
109
The character `!' in "command" are replaced with the
110
previous shell command. The sequence "\\!" is replaced by "!".
113
quit reading the current file; go on to the next (if any)
117
(dot) repeat the previous command.
119
The commands take effect immediately, i.e., it is not necessary to
120
type a carriage return.
121
Up to the time when the command character itself is given,
122
the user may hit the line kill character to cancel the numerical
123
argument being formed.
124
In addition, the user may hit the erase character to redisplay the
127
At any time when output is being sent to the terminal, the user can
128
hit the quit key (normally control\-\\).
130
will stop sending output, and will display the usual --More--
132
The user may then enter one of the above commands in the normal manner.
133
Unfortunately, some output is lost when this is done, due to the
134
fact that any characters waiting in the terminal's output queue
135
are flushed when the quit signal occurs.
137
The terminal is set to
139
mode by this program so that the output can be continuous.
140
What you type will thus not show on your terminal, except for the / and !
143
If the standard output is not a teletype, then
147
except that a header is printed before each file.
