Hello,
I'm OK with this, but since I can't verify it at all, I would be more
comfortable if one of the other AIX users would review this as well.
I'm also a bit surprised by the "wc -l | awk '{print $1}" construct. The
point of sending -l to wc is to only get the line number count as
output, yes? So why the awk part then?
