-.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.
