The exact command you executed would've been nice. -d should work and so it does for me (though this particular usecase is on an OpenBSD box). If you haven't already tried it do the following from anywhere on your system: patch -d /other/dir -i /var/tmp/tilda.diff -p0 I'm not sure if the order of the options matters, so you might have to consult patch(1). Please test the above patch command and report back as I'd say it is a bug if it doesn't work. If it didn't work please also post the full patch command and the output of head -5 /var/tmp/tilda.diff Frank.
