Looks easy enough to parse in Perl. Any reason to insist on Bash?

In BASH, I find it easier to parse through a list if you use space
delimiters. I couldn't get it to work with my standard method. I
suggest, if BASH is insisted upon and Perl must be avoided, that you use
sed/awk (probably sed more than awk).

In case you don't know (many seem to think sed is out of "fahsion"), sed
is a parser, like perl (sed stands for Stream editor). THere are some
similarities in syntax, but sed is not a language, like Perl is.
