[wplug] Line-by-line input from stdin, from a bash script ?

[Dave Ostroske]

Bash doesn't have a lot of full line processing capabilities. You might get
some things with "read" if you use the right options, but "read" will
definitely chop end-of-line spaces if you let it.

Best thing to do is hand off your line processing to other tools. I'm a fan
of awk and sed, but YMMV. Perl is good with a lot of this kind of stuff. I
love Python, others adore Ruby.

That's a very broad answer, but it was a very broad question.
