Diff and patch

This is just a quick guide for reference, use 'man' to know more.

- Back to index -

- -

- Apply a patch -

- -

- To apply a patch to a single file, do that in it's directory:
- $ patch < foo.patch -

- -

- Assuming that the patch is distributed in unified format identifying - the file the patch should be applied to, the above will work. Otherwise:
- $ patch foo.txt < bar.patch -

- -

- You can apply a patch to an entire directory, but note the "p level". - What this means is that inside patch files will be the files that you - intend to patch, identified by path names that might be different - when the files ane located on your own computer instead of on the computer - where the patch was created. 'p' level instructs the 'patch' utility to - ignore parts of the path name to identify the files correctly. Usually a - p level of 1 will work, so you would use:
- $ patch -p1 < baz.patch -

- -

- Change to the top level directory before running this. If a patch level - of 1 cannot identify the files to patch, then inspect the patch file for file names. - For example:
- /home/user/do/not/panic/yet.c -

- -

- and you are working in a directory that contains panic/yet.c, use:
- $ patch -p5 < baz.patch -

- -

- You usually count one up for each path separator (forward slash) - removed from the beginning of the path, until you are left with a path - that exists in the current working directory. The count is the p level. -

- -

- Removing a patch using the -R flag
- $ patch -p5 -R < baz.patch -

- -

- Create a patch with diff -

- -

- Diff can create a patch for a single file:
- $ diff -u original.c new.c > original.patch -

- -

- For diff'ing a source tree:
- $ cp -R original new -

- -

- Do whatever you want in new/ and then diff it:
- $ diff -rupN original/ new/ > original.patch -

- -

- git diff -

- -

- git is something special. -

- Note: this won't show new files created. -

- -

- Just make whatever changes you want to a git clone and then:
- $ git diff > patch.git -

- -

- Note the git revision that you did this with:
- $ git log -

- -

- Alternatively (better yet), commit your changes and then use:
- $ git format-patch -N
- Replace N with the number of commits that you want to show. -

- -

- git apply -

- -

it really is.

- -

- Now to apply that patch in the future, just git clone it again and do - with the git revision you found from above:
- $ git reset --hard REVISIONNUMBER -

- -

- Now put patch.git in the git clone directory and do:
- $ git apply patch.git -

- -

- If you use a patch from git format-patch, then use git am patch.git instead of git apply patch.git. git-am - will re-create the commits aswell, instead of just applying the patch. -
