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 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 possi-
     bilities 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 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
          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  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
          command.

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

     !command
          invoke a shell with command. The character `!' in "com-
          mand"  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 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

     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.
