# Creating a Patch

A patch is really just a textfile which contains a collection of lines to be added or substracted to/from other textfiles.

## Create Patch From a git Cherry Pick

[git](http://en.wikipedia.org/wiki/Git_%28software%29)
 is a source code management tool, which is becoming more and more popular. Creating a patch from a git repo is quite easy, if you know which commit(s) you are looking for.

If you know which commit includes the changes you are interested of, for instance *886600b5a2baa0c88f4d709dbc6ab0896e6565cb*, in the root of the git source, do:

| git show 886600b5a2baa0c88f4d709dbc6ab0896e6565cb |
| --- |

git show 886600b5a2baa0c88f4d709dbc6ab0896e6565cb

The result could look something like this:

```
   1

commit 886600b5a2baa0c88f4d709dbc6ab0896e6565cb

   2

```

It contains most of the info we need for patching a Debian source package. It has the actual diff that will change the source code. It also includes the author of the commit, as well as a description of the commit. All this can be used when documenting the patch.

If we were to create a patch from this, all we need to do is:

```
git show 886600b5a2baa0c88f4d709dbc6ab0896e6565cb > ../my-fix.patch
```

# Applying a patch

Applying a patch is generally done by entering the root of the source directory. Then, using the command:

```
patch -p 1 < /path/to/patch
```

See the man page for patch to learn more.
