My suggested grep has been correct Perl syntax since Perl 5.0. (Perhaps before?) Note there are no parentheses after the `grep`... not this: `grep({ ... } @list)` [download] And note that there's no comma after the block... not this: `grep { ... }, @list` [download] It just needs to be like this: `grep { ... } @list` [download] If you really want parentheses, they can go on the outside: `(grep { ... } @list)` [download] `perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'`	[reply] [d/l] [select]

I think what is breaking it for me is the `$_ eq $unique`. When I include that, real matches don't register as matches. EDIT: nevermind... typo.	[reply] [d/l]

I believe the way you have it is a correct way to do it (see grep): `grep ( /^$unique$/, @first_list_new )` [download] An alternate syntax is: `grep { /^$unique$/ } @first_list_new` [download]	[reply] [d/l] [select]

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]
