ZMORE(1) ZMORE(1)
 
 
 
NAME
       zmore - file perusal filter for crt viewing of com-
       pressed 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 termi-
       nal 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 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 win-
              dow 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). Other-
              wise, 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 regu-
              lar 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 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.
