patch is a shell command that updates text files according to instructions in a separate file, called a patch file. The patch file is a text file that lists the differences between the input file and the desired content. The command is designed to support patch files created via diff. A user creates a patch file by running diff for two versions of a file, which produces a list of differences that patch can later use to generate the target file from the original file plus the patch file. The term patch is also a verb for applying a patch.
