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 characteristics, and to  deter-
       mine  the  default window size.	On a terminal capable of displaying 24 lines, the default
       window size is 22 lines.

       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).  Otherwise, a screenful is dis-
	      played, 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.  Eras-
	      ing 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 (nor-
       mally  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.  Unfortu-
       nately, 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.
