The exit status of "cvs diff" is exactly the same as the exit status of "diff"
(man diff for more info). Why not test the exit status itself:
cvs diff blah
if [ $? -lt 2 ]
then
echo success
else
echo failure
fi

Subject: [PATCH] cvs diff exit status
When the cvs diff command is run it attempts to return one of
three status codes to main:
0 - files same
1 - files different
2 - Some sort of error has occurred
main interprets and return codes > 0 as a cvs program failure.
I've changed diff.c to return only success or failure. Success
is either the '0' or '1' state outlined above. Failure is the
'2' state.
The reason that I have done this is because the current cvs
code returns EXIT_FAILURE for both '1' and '2' outlined above.
When I run a cvs diff command and check the programs return code
I have no way of telling whether cvs ran successfully or cvs found
some diffs without parsing the output from cvs as well.
Thanks!
