In Perl, you can do:
The
/eoption causes the replacement expression to be interpreted as Perl code to be evaluated, whose return value is used as the final replacement value.lc($x)returns the lowercased version of$x. (Not sure but I assumelc()will handle international characters correctly in recent Perl versions.)/gmeans match globally. Omit thegif you only want a single replacement.
