in reply to qr// and user provided regex patterns...

ikegami provided a solution to your direct question.

An alternate approach that I usually employ is to provide another command-line option for a case-sensitive match.

my $pattern = ($options{i}) ? qr/$options{c}/i : qr/$options{c}/;

The following does a case-sensitive match:

regexTester -c 'Bill Clinton'

The following does a case-insensitive match:

regexTester -i -c 'Bill Clinton'

See Finding commands in Unix PATH for a complete example with POD instructions.

[LanX]: yes correct, but Sinai is not on the other side
