Q.I know that I can patch binary package using up2date or yum command in Linux but what I’m wondering is if there’s a way to apply a patch file to downloaded source code under Linux / UNIX like operating system source tree?
A. Linux and UNIX source software often comes with security and other patches. You can download them from Internet or project home page. There is a command called patch that apply a diff file or patch to an original source tree.
patch takes a patch file patchfile containing a difference listing produced by the diff program and applies those differences to one or more original files, producing patched versions. Normally the patched versions are put in place of the originals.
The following usage is most commonly used:
$ patch -p1 < {/path/to/patch/file}
To apply a patch, one could run the following command in a shell:
$ patch < /path/to/file
Patches can be undone, or reversed, with the '-R' option:
$ patch -R < /path/to/file
Above 3 are basic usage read the man page of patch command for more information and usage:
% man patch

guess what I need is a link to the .patch file syntax so I know what it means and can apply the changes manually (unless there’s some other way to do it).
