Hello Ksonar,

Welcome to the Monastery. Check this question (Difference between two arrays - is there a better way?), it contains all the answers to your problem.

Update: A few comments regarding the sample code that you provided.

When you compare if ( $array1[$j] =~ $array2[$k] ) you are not comparing the strings read perlop/DESCRIPTION. You should use eq for strings and == for integers. This is a binding operators =~ read more here perlop/Binding Operators.

One final note:

In Perl you do not need to loop arrays in C style for ( $j = 0 ; $j < $array1Size ; $j++ ) you can loop them through foreach my $element (@array) {} read more here perlop/Foreach Loops. In case you want to iterate over two equal size arrays you can do it like this foreach my $index ( 0 .. $#array ){} but in your case your arrays are not same in size so you can not use this method just for reference, read more here How do I Loop over multiple arrays simultaneously ?.

Hope this helps, BR.

Seeking for Perl wisdom...on the process of learning...not there...yet!
