Does the ncn_CheckDir.pl file have a white character in the name?
Check with:
Code:
ls -Q ncn_CheckDir.pl

or just
Code:
ls -Q

in the directory.
It will print quotes around the files.

What do you expect this line to do?
Code:
'exit 255' USR1

That's what I was wondering too, looks like the last half of a trap statement.

I suspect the script has comments at the top that have been cut out (for privacy etc.) along with the trap.

eg green section below:
Code:
#!/usr/bin/sh
# Eight lines
# of comment
# The OP didn't
# want to post
# to this thread -
# Perhaps for
# Privacy Reasons
#
trap 'exit 255' USR1
ncn_CheckDir.pl -a
...
