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 /usr/share/misc/termcap to deter-
       mine  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 vari-
       able 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.  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 zmore to exit.


       s      When  the  prompt  --More--(Next  file:  file)   is
              printed, this command 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).   Other-
              wise,  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" are replaced with the previous shell com-
              mand.  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 nec-
       essary 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



                                                                2

       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 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.
