In the interest of portability awareness, let me be anally correct. I don't think that awk allows a regex for field separation. However, gawk does, and it is in the manual. Of course on Linux systems, awk is typically a symlink to gawk. Good programming would be that when you require features of gawk which are not part of awk, to call the program by the name of gawk, and it will produce an obvious failure instead of rubbish results. Btw see my recent cable traffic script for an example of shell programming with gawk components, it fits in with the script talk we had last year too.
