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.  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 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 if there is more than one file.
