in reply to Re^4: Is there a way to compare strings without using an array? (say)
in thread Is there a way to compare strings without using an array?
The reason is because say is not (yet) a built-in function. You have to import the function into your namespace first, hence use feature 'say';
Alternatively, you can just use print, which does not implicitly add the new line for you like say does.
You can also add the -l (dash elle) modifier to your "shebang" line which essentially makes print behave like say:
print "$_\n" for $line1 =~ /[$line2]/g;
Hope this helps!
print for $line1 =~ /[$line2]/g;
