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  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  zmore  pauses,  and  their
       effects, are as follows (i is an optional integer argument, defaulting
       to 1) :


       i
              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.  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 com-
              mand causes zmore to exit.


       s      When the prompt --More--(Next file: file) is printed, this com-
              mand causes zmore to skip the next file and continue.


       =      Display the current line number.


       i/expr search for the i-th occurrence of the regular expression  expr.
              If the pattern is not found, zmore 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 "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  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 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-\).  Zmore will stop sending out-
       put, 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  char-
       acters  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.
