patch 命令

常用示例

说明

patch applies changes described in a patch file to original files. Patch files are typically created by diff and contain instructions for adding, modifying, or removing lines. The tool reads the patch file and attempts to apply each hunk (section of changes) to the target file. If a hunk doesn't match exactly, patch tries to find a location where it can apply with fuzz (allowing some context lines to differ). patch is essential for software development, applying updates to source code, and managing code changes distributed as patches.
