How-To question for the NC*SA brain trust...

[Gantt Edmiston]

Thanks Brett, but you didn't read the whole thing...

I tried quotes and it's not the chmod statement that's
failing.  It's the loop.  The shell is parsing each line,
seeing whitespace, and interpreting the two as
separate records.  It never get's to the chmod
line quoted or not, intact, as one line with a whitespace.
