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.
