 .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.
