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

SYNOPSIS
       zmore [ name ...  ]

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

       Zmore  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.

       Zmore looks in the file /etc/termcap to determine terminal characteris-
       tics,  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  zmore  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-\).  Zmore 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  zmore  acts  just  like
       zcat, except that a header is printed before each file if there is more
       than one file.
