[Message part 1 (text/plain, inline)]

Hi together,
I'm new to this list and hope to be at the right place.

I'd like to know if there's a possibility within GNU diff (I checked
diffutils 3.2) to fail fast (i.e. return with and exit code != 0) after
the first difference has been found in the file or any file (in a
recursive diff). I know that I could listen to output on stdout, but
this wouldn't be within diff.

Kind regards,
Karl-P. Richter

There isn't an option to do that now, but it'd make sense to add one.
