项目历史

The GNU patch README states that this GNU version applies diff files to original files and includes many Free Software Foundation changes: binary and large-file handling, unified diff support, merge behavior, GNU-style backup files, improved RCS and SCCS interaction, GNU option parsing/configure conventions, and better POSIX compliance.

The README also explains why the FSF distributed GNU patch independently: Larry Wall had not released a new version since mid-1988, and he agreed to GNU distribution under the GNU General Public License. GNU bulletins from the 1990s describe patch as GNU's version of Larry Wall's program for applying diff output.

采用历史

patch became a standard Unix packaging primitive because source distributions could ship small textual changes instead of whole replacement trees. GNU patch's support for unified diffs, reject files, backup naming, and POSIX/GNU build conventions made it fit naturally into Autotools-era source packages and distribution build recipes.

使用方式

The GNU diffutils manual shows the common form `patch <patchfile`, with optional original-file and patch-file arguments. If no patch file is supplied, patch reads diff output from standard input; if no input file is supplied, it tries to infer the file to edit from leading patch text.

为什么软件包爱好者会关心

For package maintainers, GNU patch is infrastructure rather than just a user command. It is the tool behind downstream patch queues, source RPM and Debian patch application, vendor backports, portability fixes, and decades of email-driven source exchange before pull-request platforms normalized repository-hosted review.
