Otherwise:<br/> - <b>$ patch foo.txt < bar.patch</b> - </p> - - <p> - 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:<br/> - <b>$ patch -p1 < baz.patch</b> - </p> - - <p> - 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:<br/> - <b>/home/user/do/not/panic/yet.c</b> - </p> - - <p> - and you are working in a directory that contains panic/yet.c, use:<br/> - <b>$ patch -p5 < baz.patch</b> - </p> - - <p> - 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. - </p> - - <p> - Removing a patch using the -R flag<br/> - <b>$ patch -p5 -R < baz.patch</b> - </p> - - <p><a href="#pagetop">Back to top of page.</a></p> - - </div> - - <div class="section"> - - <h1> - Create a patch with diff - </h1> - - <p> - Diff can create a patch for a single file:<br/> - <b>$ diff -u original.c new.c > original.patch</b> - </p> - - <p> - For diff'ing a source tree:<br/> - <b>$ cp -R original new</b> - </p> - - <p> - Do whatever you want in new/ and then diff it:<br/> - <b>$ diff -rupN original/ new/ > original.patch</b> - </p> - - <p><a href="#pagetop">Back to top of page.</a></p> - - </div> - - <div class="section"> - - <h1> - git diff - </h1> - - <p> - git is something special. - </p> - <p> - Note: this won't show new files created. - </p> - - <p> - Just make whatever changes you want to a git clone and then:<br/> - <b>$ git diff > patch.git</b> - </p> - - <p> - Note the git revision that you did this with:<br/> - <b>$ git log</b> - </p> - - <p> - Alternatively (better yet), commit your changes and then use:<br/> - $ <b>git format-patch -N</b><br/> - Replace N with the number of commits that you want to show. - </p> - - <p><a href="#pagetop">Back to top of page.</a></p> - - </div> - - <div class="section"> - - <h1> - git apply - </h1> - - <p>it really is.</p> - - <p> - Now to apply that patch in the future, just git clone it again and do - with the git revision you found from above:<br/> - <b>$ git reset --hard REVISIONNUMBER</b> - </p> - - <p> - Now put patch.git in the git clone directory and do:<br/> - <b>$ git apply patch.git</b> - </p> - - <p> - If you use a patch from git format-patch, then use <b>git am patch.git</b> instead of <b>git apply patch.git</b>. git-am - will re-create the commits aswell, instead of just applying the patch. - </p> - - <p><a href="#pagetop">Back to top of page.</a></p> - - </div> - - <div class="section"> - - <p> - Copyright © 2014, 2015 Francis Rowe <info@gluglug.org.uk><br/> - Permission is granted to copy, distribute and/or modify this document - under the terms of the GNU Free Documentation License, Version 1.3 - or any later version published by the Free Software Foundation; - with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. - A copy of the license can be found at <a href="../gfdl-1.3.txt">../gfdl-1.3.txt</a> - </p> - - <p> - Updated versions of the license (when available) can be found at - <a href="https://www.gnu.org/licenses/licenses.html">https://www.gnu.org/licenses/licenses.html</a> - </p> - - <p> - 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.
