Re^2: searching in array elements substrings contained in another array

Thank you for the ultrafast reply... but it seems it soesn't work... Or better: the first cycle works, but when it comes to use the previously processed array (@triple), a long list of warning comes:

 Use of uninitialized value in pattern match (m//)
[download]

and the matches don't work. Printing the two arrays gives that the matches have not been removed... Any idea? Thank you again Livius

How can `undef` values fall into `@triple` array? Anyway here is the fix: `foreach my $q (@quadruple) { @triple = grep {$_ and $q !~ /$_/} @triple; }` [download]	[reply] [d/l] [select]
