c)it will save that output to /tmp/result..

but my script is just hanging...

#!/usr/bin/perl -w

open(SIPFILE, "</tmp/sipfile")
or die "Couldn't find the /tmp/sipfile: $! \n";
open(RESULT, ">>/tmp/result");

plot

PLOT(1G)																  PLOT(1G)

NAME

       plot - graphics filters

SYNOPSIS

       plot [ -Tterminal [ raster ] ]

DESCRIPTION

       These  commands read plotting instructions (see plot(5)) from the standard input, and in general produce plotting instructions suitable for
       a particular terminal on the standard output.

       If no terminal type is specified, the environment parameter $TERM (see environ(5)) is used.  Known terminals are:

       4014   Tektronix 4014 storage scope.

       450    DASI Hyterm 450 terminal (Diablo mechanism).

       300    DASI 300 or GSI terminal (Diablo mechanism).

       300S   DASI 300S terminal (Diablo mechanism).

       ver    Versatec D1200A printer-plotter.	This version of plot places a scan-converted image  in	`/usr/tmp/raster'  and	sends  the  result
	      directly	to  the  plotter device rather than to the standard output.  The optional argument causes a previously scan-converted file
	      raster to be sent to the plotter.

FILES

       /usr/bin/tek
       /usr/bin/t450
       /usr/bin/t300
       /usr/bin/t300s
       /usr/bin/vplot
       /usr/tmp/raster

SEE ALSO

       plot(3), plot(5)

BUGS

       There is no lockout protection for /usr/tmp/raster.
