If there's a better solution to stripping a leading space out of
something parsed with awk on a character other than a space that can
strip whitespace that would also be helpful.


If there's some way to do this in the original awk line I'd still like
to hear about it.


Something along the lines of:

$ echo " a test" | awk '{sub("^ ", "", $0); print $0}' a test

Cool.

Yes sub works a lot better and with less code.

Thanks all.
