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 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<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 (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 sig-
       nal 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  termi-
       nal, 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.
