BTW, why is ! better than ^ here? Just curious.
I found the answer myself. Quoting the portable shell chapter in the autoconf manual: | 11.5 Shell Pattern Matching | | Nowadays portable patterns can use negated character classes | like ‘[!-aeiou]’. The older syntax ‘[^-aeiou]’ is supported | by some shells but not others; hence portable scripts should | never use ‘^’ as the first character of a bracket pattern. Cheers, Peter
