NAME
       gzmore - file perusal filter for crt viewing of compressed text

SYNOPSIS
       gzmore [ name ...  ]

DESCRIPTION
       Gzmore is a filter which allows examination of compressed or plain text
       files one screenful at a time on a soft-copy terminal.  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  character-
       istics,  and to determine the default window size.  On a terminal capa-
       ble 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) :

       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.

       is     skip i lines and print a screenful of lines

       if     skip i screenfuls and print a screenful of lines

       q or Q Quit.

       =      Display the current line number.

       i/expr search  for  the i-th occurrence of the regular expression expr.
              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" is
              replaced with the previous shell command.  The sequence "\!"  is
              replaced by "!".

       :q or :Q
              Quit (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 charac-
       ter 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
       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 gzmore acts just like
       gzcat, except that a header is printed before each  file  if  there  is
       more than one file.
