The apply-patch-to-file script allows you to apply a Git patch to files with the same content but different name or file path without having to manually modify the patch itself.

• Github Download
• Download Github Repository

Prepare each commit with its patch in one file per commit, formatted to resemble UNIX mailbox format. The output of this command is convenient for e-mail submission or for use with git.

Instructions

Use with the following syntax:

Not specifying any options defaults to interactive mode.

Options

• -ffile_to_patch — allows you to specify a single file that will be patched. This means that the specified patch must only modify one file.
• -i — starts your favorite editor with a pre-formatted table in which you specify target files that will be patched.
• -h — displays usage information.

Example

1. Create a patch of, for example, the HEAD commit in your Git repository:

2. Switch to a different repository in which you'd like to apply the patch to a file or files of your choosing, and run apply-patch-to-file script, specifying the previously-created patch as an argument:

3. In your editor, specify the target files where the patch should apply:

4. Save and exit you editor. In case of no conflicts, check git log to see your patch applied.
