Making the fifo's for SAOtng ============================ > cd ~/iraf > cd dev > /usr/sbin/mknod imt1i p > /usr/sbin/mknod imtio p > chmod 600 imt1i imt1o > sed s+imtool,,+imtool,$cwd/imt1,+g /applic/nir/iraf/iraf211/dev/graphcap > mygraphcap # This is all one line. Then make sure in your .cshrc (or .alias file if .cshrc sources it) that you have the line: alias saotng "saotng -input_fifo ${HOME}/iraf/imt1i -output_fifo \ ${HOME}/iraf/imt1o" This makes it so you can run SAOtng.
