You should be able to run sdiff with either the [open][1] function
open my $pipe, "-|", "sdiff", "file1", "file2"
or die "could not run sdiff: $!";
while (my $line = <$pipe>) {
#do stuff
}
or [backticks][2]
for my $line (`sdiff file1 file2`) {
#do stuff
}
For removing identical lives, I would look at [regexes][3] or [substr][4].
If you wish for this program to be written for you, I can send you a rate card.
