Usually patch is done by:
diff -Naur file1 file2 > patch.1
And to patch file2:
patch < patch.1
Now let's assume that I want to patch file2 with the differences from file1. However all the initial differences of file2 I want to keep.
In other words I want to apply only '+' changes in patch.1 but not to apply '-'.
Is it possible ? And if yes, how can I do this...
