This is exactly the sort of of pain experience would lead me to

OK, this is where I assume the full Old Fart position (30-year
old-school Unix guy, author of "The Art of Unix Programming", can
remember the years before Perl and still has sh idioms in his
fingertips) and say "Get with the 21st century, people! Or at least

As a general scripting language shell sucks *really badly* compared to
anything new-school. Performance, portability, you name it, it's a
mess.  It's not so much the shell interpreters itself that are the
portabilty problem, but (as Magnus implicitly points out) all those
userland dependencies on sed and tr and awk and even variants of
expr(!) that get dragged in the second you try to get any actual work

Can we cease behaving like we're still pounding keys on 110-baud
teletypes now?  Some old-school Unix habits have persisted long past
the point that they're even remotely sane.  Shell programming at any
volume above a few lines of throwaway code is one of them - it's
*nuts* and we should *stop doing it*.

(Yes, I too still make this mistake occasionally out of ancient reflex.
But I know I shouldn't, and I always end up regretting it.)
