BTW the -E/--extended-regexp flag makes it easier: grep -E 'inet6?' | ...
And what I learned today, sed has -r/--regexp-extended (don't you love consistent tools?)
In this case I might rather do all the parsing in YCP/Perl/Ruby and omit using grep/sed.

Everyone raise your mouse cursor if you've ever reimplemented this function ;-)
OK, reinvented Wheel replaced with Wheel 2.0. In fact, this String::XYZ should rather be a built-in ...
