Removing entries in array based on another array

[Leif Wessman]

I would like to remove the complete entry in an array if the value of
the entry matches any of the values in another array.

Like this:

use strict;
use warnings;

my @names ("bob","barney","-","lisa","UNKNOWN");
my @delete ("-","unknown");

....

result should be that @names contains only bob, barney and lisa.
Thanks for any input!

perldoc -q duplicate

That finds "How can I remove duplicate elements from a list or array?",
which doesn't deal with the OPs problem, tough it might help.
The one that deals with the problem directly is found through

perldoc -q difference

"How do I compute the difference of two arrays?"

Of course, thanks! Sorry Leif for pointing you to the wrong FAQ entry.
Maybe I should check the FAQ before posting such a comment... ;-)
