ZMORE(1)                                       General Commands Manual                                       ZMORE(1)



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 dis‐
       played.  Other possibilities are enumerated later.

       Zmore looks in the file /etc/termcap to determine terminal characteristics, and to determine the default  win‐
       dow  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 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 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  com‐
              mand.  The sequence "\!" is replaced by "!".

       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.
