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 characteris-
       tics,  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 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  com-
              mand causes zmore to exit.


       s      When  the prompt --More--(Next file: file) is printed, this com-
              mand 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 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 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 charac-
       ter 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.
