Right. Thanks.

Gnome allows me to run my bash script in a terminal so now the terminal pops up, runs gigdump, greps out the right lines and saves them to a temp file. I then cat that file to the same terminal and see the results.

Not into GUI programming today. Just want to see if I can get it to work.

Jsut happening in an xterm is fine for me. Thanks, MArk -- [email protected] mailing list
