Subject: Need help with RE:
Hi,
my $line = "Unconfirmed";
I need an RE that will give me a TRUE value if the string is 2~8 chars long.
otherwise, it gives FALSE;
I tried
if ($line =~ /\S{2,8}/) {
?? return 1;
} else {
?? return 0;
}
However this does not work.
I cannot use length($line) because it has to be Regular expression.
Thanks.
