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

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

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

     Bzmore is a filter which allows examination of compressed or
     plain text files one screenful at a time on a soft-copy ter-
     minal.  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) :

          display i more lines, (or another screenful if no argu-
          ment 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

     is   skip i lines and print a screenful of lines

     if   skip i screenfuls and print a screenful of lines

          search for the i-th occurrence of the  regular  expres-
          sion 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

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

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

          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 neces-
     sary 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 (normally 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.  Unfortunately, some  output  is  lost
     when this is done, due to the fact that any characters wait-
     ing in the terminal's output queue are flushed when the quit

     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
