     gzmore  -  file perusal filter for crt viewing of compressed

     gzmore [ name ...  ]

     Gzmore is a filter which allows examination of compressed or
     plain text files one screenful at a time on a soft-copy ter-
     minal.  gzmore works on files compressed with compress, pack
     or gzip, and also on uncompressed files.  If a file does not
     exist, gzmore looks for a file of the  same  name  with  the
     addition of a .gz, .z or .Z suffix.

     Gzmore   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.

     Gzmore  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.  To use  a  pager  other  than  the
     default  more, set environment variable PAGER to the name of
     the desired program, such as less.

     Other sequences which may be typed when gzmore  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

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

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

     =    Display the current line number.

          search  for  the i-th occurrence of the regular expres-
          sion expr.  If the pattern is not found, gzmore 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" is 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-\).  Gzmore 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  gzmore  acts
     just like gzcat, except that a header is printed before each
