A patch may or may not work, and may or may not eventually be incorporated permanently into the program. Distinguished from a diff or mod by the fact that a patch is generated by more primitive means than the rest of the program; the classical examples are instructions modified by using the front panel switches, and changes made directly to the binary executable of a program originally written in an HLL. Compare one-line fix. 2. To insert a patch into a piece of code. 3. [in the Unix world] A diff. 4. A set of modifications to binaries to be applied by a patching program. IBM systems often receive updates to the operating system in the form of absolute hexadecimal patches. If you have modified your OS, you have to disassemble these back to the source code. The patches might later be corrected by other patches on top of them patches were said to "grow scar tissue". The result was often a convoluted patch space and headaches galore. There is a classic story of a tiger team penetrating a secure military computer that illustrates the danger inherent in binary patches or, indeed, any patches that you cant - or dont - inspect and examine before installing. They couldnt find any trap doors or any way to penetrate security of IBMs OS, so they made a site visit to an IBM office remember, these were official military types who were purportedly on official business, swiped some IBM stationery, and created a fake patch. The patch was actually the trapdoor they needed. The patch was distributed at about the right time for an IBM patch, had official stationery and all accompanying documentation, and was dutifully installed. The installation manager very shortly thereafter learned something about proper procedures. 5. Larry Walls "patch" utility, which automatically applies a patch to a set of source code or other text files. It accepts input in any of the four forms output by the Unix diff utility and uses many helpful heuristics to determine how to apply them. Diff and patch are the standard way of producing and applying updates to Unix files ditributed via Usenet and the Internet, both have been ported to other operating systems.
