That did the trick! I modified it to fit of course, but that did the trick. Thank you very much!

I also removed
Code:
set ${ID}

per Nitrodist's suggestion. I don't think it was really doing anything.

That crams the entire file into a variable, which may silently ignore anything too large to fit in one shell variable.

If you have BASH:
Code:
while read -d , VAR
do
        echo $VAR
done < filename

If you don't, a temp file:

Code:
tr -d ',' '\n' < infile > /tmp/$$
while read VAR
do
        echo "$VAR"
done < /tmp/$$
rm -f /tmp/$$
