Not too sure about the other bits but I've never gotten it to run with the Load/Run app.

My script is called mount_floorPC.sh and I've dumped it in /root. (Bad, I know)

The commandline for the Load/Run app is '/root/mount_floorPC.sh'. I've tried 'sh /root/mount_floorPC.sh' as well but no dice.

So far as setting the path (Dunno if this'll work on the 770, Redhat accepts this tho):

PATH=/mydir1:/mydir2:/mydir3; export PATH;
