.TH BZMORE 1 |
|
.SH NAME |
|
bzmore, bzless \- file perusal filter for crt viewing of bzip2 compressed text |
|
.SH SYNOPSIS |
|
.B bzmore |
|
[ name ... ] |
|
.br |
|
.B bzless |
|
[ name ... ] |
|
.SH NOTE |
|
In the following description, |
|
.I bzless |
|
and |
|
.I less |
|
can be used interchangeably with |
|
.I bzmore |
|
and |
|
.I more. |
|
.SH DESCRIPTION |
|
.I Bzmore |
|
is a filter which allows examination of compressed or plain text files |
|
one screenful at a time on a soft-copy terminal. |
|
.I bzmore |
|
works on files compressed with |
|
.I bzip2 |
|
and also on uncompressed files. |
|
If a file does not exist, |
|
.I bzmore |
|
looks for a file of the same name with the addition of a .bz2 suffix. |
|
.PP |
|
.I Bzmore |
|
normally pauses after each screenful, printing --More-- |
|
at the bottom of the screen. |
|
If the user then types a carriage return, one more line is displayed. |
|
If the user hits a space, |
|
another screenful is displayed. Other possibilities are enumerated later. |
|
.PP |
|
.I Bzmore |
|
looks in the file |
|
.I /etc/termcap |
|
to determine terminal characteristics, |
|
and to determine the default window size. |
|
On a terminal capable of displaying 24 lines, |
|
the default window size is 22 lines. |
|
Other sequences which may be typed when |
|
.I bzmore |
|
pauses, and their effects, are as follows (\fIi\fP is an optional integer |
|
argument, defaulting to 1) : |
|
.PP |
|
.IP \fIi\|\fP<space> |
|
display |
|
.I i |
|
more lines, (or another screenful if no argument is given) |
|
.PP |
|
.IP ^D |
|
display 11 more lines (a ``scroll''). |
|
If |
|
.I i |
|
is given, then the scroll size is set to \fIi\|\fP. |
|
.PP |
|
.IP d |
|
same as ^D (control-D) |
|
.PP |
|
.IP \fIi\|\fPz |
|
same as typing a space except that \fIi\|\fP, if present, becomes the new |
|
window size. Note that the window size reverts back to the default at the |
|
end of the current file. |
|
.PP |
|
.IP \fIi\|\fPs |
|
skip \fIi\|\fP lines and print a screenful of lines |
|
.PP |
|
.IP \fIi\|\fPf |
|
skip \fIi\fP screenfuls and print a screenful of lines |
|
.PP |
|
.IP "q or Q" |
|
quit reading the current file; go on to the next (if any) |
|
.PP |
|
.IP "e or q" |
|
When the prompt --More--(Next file: |
|
.IR file ) |
|
is printed, this command causes bzmore to exit. |
|
.PP |
|
.IP s |
|
When the prompt --More--(Next file: |
|
.IR file ) |
|
is printed, this command causes bzmore to skip the next file and continue. |
|
.PP |
|
.IP = |
|
Display the current line number. |
|
.PP |
|
.IP \fIi\|\fP/expr |
|
search for the \fIi\|\fP-th occurrence of the regular expression \fIexpr.\fP |
|
If the pattern is not found, |
|
.I bzmore |
|
goes on to the next file (if any). |
|
Otherwise, a screenful is displayed, starting two lines before the place |
|
where the expression was found. |
|
The user's erase and kill characters may be used to edit the regular |
|
expression. |
|
Erasing back past the first column cancels the search command. |
|
.PP |
|
.IP \fIi\|\fPn |
|
search for the \fIi\|\fP-th occurrence of the last regular expression entered. |
|
.PP |
|
.IP !command |
|
invoke a shell with \fIcommand\|\fP. |
|
The character `!' in "command" are replaced with the |
|
previous shell command. The sequence "\\!" is replaced by "!". |
|
.PP |
|
.IP ":q or :Q" |
|
quit reading the current file; go on to the next (if any) |
|
(same as q or Q). |
|
.PP |
|
.IP . |
|
(dot) repeat the previous command. |
|
.PP |
|
The commands take effect immediately, i.e., it is not necessary to |
|
type a carriage return. |
|
Up to the time when the command character itself is given, |
|
the user may hit the line kill character to cancel the numerical |
|
argument being formed. |
|
In addition, the user may hit the erase character to redisplay the |
|
--More-- message. |
|
.PP |
|
At any time when output is being sent to the terminal, the user can |
|
hit the quit key (normally control\-\\). |
|
.I Bzmore |
|
will stop sending output, and will display the usual --More-- |
|
prompt. |
|
The user may then enter one of the above commands in the normal manner. |
|
Unfortunately, some output is lost when this is done, due to the |
|
fact that any characters waiting in the terminal's output queue |
|
are flushed when the quit signal occurs. |
|
.PP |
|
The terminal is set to |
|
.I noecho |
|
mode by this program so that the output can be continuous. |
|
What you type will thus not show on your terminal, except for the / and ! |
|
commands. |
|
.PP |
|
If the standard output is not a teletype, then |
|
.I bzmore |
|
acts just like |
|
.I bzcat, |
|
except that a header is printed before each file. |
