Solved how to create patches using diff without copy of original file

[jindam]

* right now i am creating .patches using

diff -u OriginalFile UpdatedFile > PatchFile

* however, if i list original file,
patches will be useless
* how do i create patches without
need to keep of original file?

• example_
• i will make 10 edits to a file

along with patches, edit1.patch,
edit2.patch .... edit10.patch and
i have latest edited file: file.txt
* i want to view what i have added
in 7th patch, is it possible to
apply edit7.patch on file.txt with
discarding changes from edit8.patch?

No you can't. You need the original. You can't patch what you don't have.

diff -u original_file.c updated_file.c > mypatch.patch

This will create a unified diff format patch file named mypatch.patch.

patch original_file.c < mypatch.patch
This will apply the patch.

It's best to have the patch and the original file in the same directory. If they aren't you can do this...

patch -p1 < mypatch.patch

The -p1 strips the leading paths.
