Thanks dr.house . Overall that site doesn't look too bad if you only write for bash. Most of the time they avoid constructs which easily break like:
Code:
for i in `ls -1R`

Back on topic.

The original problem with:
Code:
for line in `cat Results.txt`

The "cat" executes first and create a very wide "for line in" statement with lots of fields made up from the entire contents of Results.txt:
The field separator in "for" is a space character.
The "for" loop executes once for every space separated field. Thus $line never contains the whole record. In fact $FIELD2 only contains something if the contents of $line happen to contain a pipe character.
