Using GNU diff in a PERL Script

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi all, I am trying to write a script that will use diff. I have looked at the CPAN diff version and just do not like it as much, is there a way to use the GNU version of diff in a PERL Script? Thanks!

`my $diff = qx\| diff file1 file2 \|;` [download] Another syntax would be using backticks - see perldoc perlop.	[reply] [d/l]

Which specific diff on CPAN do you not like - I found several candidates...some of which are (claimed to be) compatible with patch. A user level that continues to overstate my experience :-))	[reply]

It's not really perfect, but this worked for me: Htmlify code with differences.	[reply]
