As indicated by hbm above, the next thing to try is to edit the contents of "nap_run.tcl":

source /root/nfs_share/SCRIPTS/resource.conf
source /root/nfs_share/SCRIPTS/init.tcl
[download]

It's curious that your "nap_run.tcl" file is actually being used/interpreted as a (ba)sh shell script, despite the fact that the ".tcl" extension would lead a casual observer to think that it's actually a tcl script instead. Is it your intention to use the ".tcl" extension on shell scripts? And if "resource.conf" and "init.tcl" don't start with shebang lines, is it your intention that they are also used/interpreted as shell scripts?
