Re^5: diff not working as it should

you have two lines of code, so it should be easy to choose... start just in the third line

open the output file
enter a loop reading line by line
print only the matching lines
close and reopen 
send it again to the file
and you have it.

Yes, I understand -- and have gone ahead -- and did the regex with some extra code after the diff(). And I thank you for your input. I was just wondering if there was some way to do the regex within the diff command or diff command options (I don't see anything at first glance.) Cheers!	[reply]

Well, maybe I can save you some work. If you want to do this, I suggest you to use Algorithm::Diff in its place The example script "diff.pl" provided with the module Algorithm::Diff does exactly what you want and is ready to use. You will find it in the directory after unzip and untar this package (you will need to install the module before to be able to use it, of course): `diff.pl file1 file2 ___ 5+ this is the line 5 (in file 1) 5- this is the lime 5 (in file 2)` [download]	[reply] [d/l]
