I was under the impression that IFS was the Internal Field Separator. It's a
variable in /bin/sh. It was used before awk and perl were (mercifully)
invented so that you sould do easy splitting of strings. It's usually set
to " " but you might set it to, say ":" if you were trying to peek at the
/etc/passwd file. Read pages 153-154 in the ORA Practical Unix Security
book, it's really quite good (and interesting)
