Or simply use basename -- or if your shell understands ${a##*/} then by all means use that.

The awk command splits its input into the character specified by the -F option (in this case "/"). So awk sees something like:
disk1 net first.ksh
Awk has an internal variable named "NF" which stands for the Number of Fields on the current line. In this case that's 3. So it's like writing:
awk '{ print $3 '}
which would print the third field of the input. Of course, it's not really 3 every time, just this time. So the last part of the path gets printed.
