Question

I added a new file in “modified directory” (in 3rd sub level folder) and when i try to generate the patch file using the following command it appears that diff command is ignoring the new file:

diff –ur "original directory" "modified directory" > version1.patch

I appreciate your help..

You also need -N flag. From man diff:

   -N  --new-file
          Treat absent files as empty.

When generating patches, the “standard” diff flags are -Npur. You’ve already discovered why you need -N; -p makes the patch easier for humans to read.
