Compare text files and keep only the DIFFERENT lines?
David.P:
Thanks! Sounds as if this is the right thing for me -- only a little drawback for users like me that are spoiled by mouse and blinkenlights --> seems as if there is no GUI.
But thank you very much for the tip!
Cheers David.P
Merida:
+1 for Winmerge
David.P:
Yeah thanks -- but how am I supposed to do that in Winmerge? Have looked around all menus and options but can't seem to find a "select" or "keep only different lines" option.
cranioscopical:
Another, GUI-if-desired alternative might be Beyond Compare.
With it, you could load your files and merge the differences into one, which might satisfy your needs.
rjbull:
If I understand you (and the comm utility) correctly, I think you might want comm rather than diff. It's another non-GUI command-line tool ported originally from Unix.
--- ---Usage: comm [OPTION]... LEFT_FILE RIGHT_FILE
Compare sorted files LEFT_FILE and RIGHT_FILE line by line.
-1 suppress lines unique to left file
-2 suppress lines unique to right file
-3 suppress lines that appear in both files
--help display this help and exit
--version output version information and exit.

You'd want the -3 switch, leaving only the lines that aren't common to both files. Usually, you have to sort the files first for this kind of utility to work as expected.
