Hi there,
Hello,
I am hoping to figure out the best Way to write something. I have two
arrays @previous_hostnames and @hostnames.
I want to figure out if there is at least one matching element in
@previous_hostnames that is found in @hostnames.
my $found = map { my $x = $_; grep $x eq $_, @previous_hostnames }
@hostnames;
