Need Help??

That's not a search for an exact string though. $unique might contain regexp metacharacters like ".".

perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'

Ah yes! Good point. Thanks. EDIT: But wait.... Your suggestion of `grep { $_ eq $unique } @first_list_new` isn't detecting any actual matches for me. EDIT #2: Nevermind... tyop. er, typo.	[reply] [d/l]

It's not clear why this would be. grep {$_ eq $unique} should be exactly equivalent to grep /^$unique$/, as long as $unique doesn't have any regex metacharacters--and it doesn't appear to in the sample data. When's the last time you used duct tape on a duct? --Larry Wall	[reply]

Whoa, you are write. I had a typo. I left the `//`'s around `$unique`. Oops. Maybe that means it is bedtime for me!	[reply] [d/l] [select]
