Re^3: How to grep exact string

I believe the way you have it is a correct way to do it (see grep):

grep ( /^$unique$/, @first_list_new )

An alternate syntax is:

grep { /^$unique$/ } @first_list_new

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'`	[reply] [d/l]

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]
