I dare to bet that speedwise, diff the command line program will run circles around Algorithm::Diff.

    First of all, thanks Monks for your suggestions. This is what worked for me-

    use File::Compare; open( DIFFFILE, ">> $diffFile" )|| die " cannot open $diffFile +file !!\n"; print DIFFFILE "Modified Files \n"; print DIFFFILE "<br>\n"; print DIFFFILE "=========== \n"; print DIFFFILE "<br>\n"; if (scalar(@modarry) >= 1) { foreach $f (@modarry) { print DIFFFILE "<br>\n"; print DIFFFILE "$f \n"; print DIFFFILE "<br>\n"; } }elsif (scalar(@modarry) < 1) { print DIFFFILE "\t\n None \n"; print DIFFFILE "<br>\n"; } close (DIFFFILE); foreach $f (@modarry) { @the_string=`diff -r $some_dir/$f $other_dir/$f`; open( DIFFFILE, ">> $diffFile" )|| die " cannot open $diffFile + file !!\n"; print DIFFFILE "<br>\n"; print DIFFFILE "File being diff'd: $f \n"; }

    use File::Compare, to get the list of modified files between two dirs, then run the diff command. Not efficient but it did work

      if (compare("$some_dir/$f","$other_dir/$f") != 0) { print "\n pushing $f to modarray\n"; push @modarry, $f;

      sorry I did not post the actual compare that I used
