- .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 (fIifP 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 fIifP 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.
