Hi John,
Interesting links. One thing to remember about [[]] is that its = operator
isn't a simple string comparison, as test(1)'s/[(1)'s is, and it doesn't treat
both operands the same.
$ t() { echo true; }
$ [[ hello? = hello? ]] && t
true
$ [[ hellox = hello? ]] && t
true
$ [[ hello? = hellox ]] && t
$ [[ hellox = hellox ]] && t
true
$
Cheers,
Ralph.
