NAME
       bzmore, bzless - file perusal filter for crt viewing of bzip2 compressed text

SYNOPSIS
       bzmore [ name ...  ]
       bzless [ name ...  ]

NOTE
       In  the  following  description,  bzless and less can be used interchangeably with bzmore and
       more.

DESCRIPTION
       Bzmore is a filter which allows examination of compressed or plain text files  one  screenful
       at  a  time on a soft-copy terminal.  bzmore works on files compressed with bzip2 and also on
       uncompressed files.  If a file does not exist, bzmore looks for a file of the same name  with
       the addition of a .bz2 suffix.

       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.

       Bzmore looks in the file /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 bzmore pauses, and their effects,
       are as follows (i is an optional integer argument, defaulting to 1) :

       i<space>
              display i more lines, (or another screenful if no argument is given)

       ^D     display 11 more lines (a ``scroll'').  If i is given, then the scroll size is  set  to
              i.

       d      same as ^D (control-D)

       iz     same  as  typing a space except that i, if present, becomes the new window size.  Note
              that the window size reverts back to the default at the end of the current file.

       is     skip i lines and print a screenful of lines

       if     skip i screenfuls and print a screenful of lines

       q or Q quit reading the current file; go on to the next (if any)

       e or q When the prompt --More--(Next file: file) is printed, this command  causes  bzmore  to
              exit.

       s      When  the  prompt  --More--(Next file: file) is printed, this command causes bzmore to
              skip the next file and continue.

       =      Display the current line number.

       i/expr search for the i-th occurrence of the regular expression expr.  If the pattern is  not
              found, 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.

       in     search for the i-th occurrence of the last regular expression entered.

       !command
              invoke a shell with command.  The character `!' in "command"  are  replaced  with  the
              previous shell command.  The sequence "\!" is replaced by "!".

       :q or :Q
              quit reading the current file; go on to the next (if any) (same as q or Q).

       .      (dot) repeat the previous command.

       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.

       At any time when output is being sent to the terminal, the user can hit the  quit  key  (nor‐
       mally  control-\).   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.   Unfortu‐
       nately, 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.

       The terminal is set to 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.

       If  the  standard  output  is not a teletype, then bzmore acts just like bzcat, except that a
       header is printed before each file.
