I would. I cannot imagine any shell anyone is likely to really use
which doesn't support that.
$() is less prone to errors (1, Command Substitution).
Excellent. Thanks. I only used the backticks because they'd already
been used in that script, and I couldn't remember how strict we were
being about our build environment.
I'll change them all to $(...). I haven't personally used a backtick
in my own scripts for... decades? I'd actually forgotten the baroque
behavior of backlash quoting.
And echo --> printf. Again, I was nervous about introducing it.
