format-patch for a single file

I have a file called test_module.c that has some differences that I want to apply to my local working copy.

I tried to create patch file from the remote by doing the following. However, git didn’t complain about any errors. And didn’t create any patch file either.

  • Simultaneous Git Pull On Same Server & Directory & User
  • Tower (GIT) custom script?
  • Ignore the .gitignore file itself
  • Git Edits “Lost in Space”
  • Collaborate using git and separate branches without adding a bunch of redundant commits
  • Cannot push from user repository to master repository located on NAS
  • git format-patch master/dev_branch test/test_module.c
    

    It is possible to create a patch of a single file, that I can apply?

    (Using git version 1.7.5.4)

    If you give git format-patch a single revision, it will produce patches for each commit since that revision. If you see no output from that command, then I suspect that there were no changes to that file between origin/master and your current HEAD. As an alternative, you can provide a revision range (e.g. origin/master~3..origin/master) which covers the changes introduced to that file. Or, if the changes you want to produce a patch for are just contained in the single commit at the tip of origin/master, you can use the -1 parameter, as in:

    git format-patch -1 origin/master test/test_module.c
    

    You can use following syntax for creating patch for single file:

    git format-patch [commit_hash] [file]
