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 ter-
       minal.  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 car-
       riage 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 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 argu-
       ment, 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 con-
              tinue.

       =      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  com-
       mand  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  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.
