CentOS - Sep 2009 - patching from different directory

Howdy,

I have a diff file in my /var/tmp and would like to apply patch to a
file in a different directory (other than /va/tmp). I tried using
patch with -d switch, but that doesn't work. It complains abt  'patch:
**** Can't open patch file tilda.diff : No such file or directory'. Do
I need to copy my diff file to the directory where original file
resides? Or is there any other way round?

Try:

cd /path/to/file/to/be/patched
patch -p0 </var/tmp/tilda.diff

You might want to use -p1 or -p2 or -p3... depending on what is the
path to the file inside the .diff file. To figure that out, open the
.diff file and look at the lines that start with --- and +++, then see
how many directories are there before the filename, use that number
for the argument to -p.

HTH,

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
