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. - -Copyright © 2014, 2015 Leah Rowe <info@minifree.org>\ -Permission is granted to copy, distribute and/or modify this document -under the terms of the Creative Commons Attribution-ShareAlike 4.0 -International license or any later version published by Creative -Commons; A copy of the license can be found at -[../cc-by-sa-4.0.txt](../cc-by-sa-4.0.txt) - -Updated versions of the license (when available) can be found at -<https://creativecommons.org/licenses/by-sa/4.0/legalcode> - -UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE EXTENT -POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS AND -AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND -CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, IMPLIED, STATUTORY, -OR OTHER.
