Unzip will list, test, or extract files from a ZIP archive, commonly found on MS-DOS systems. The default behavior (with no options) is to extract into the current directory (and subdirectories below it) all files from the specified ZIP archive. Unzip is compatible with archives created by PKWARE's PKZIP, but in many cases the program options or default behaviors differ. Zipinfo lists technical information about files in a ZIP archive, most commonly found on MS-DOS systems. Such information includes file access permissions, encryption status, type of compression, version and operating system or file system of compressing program, and the like. Funzip acts as a filter; that is, it assumes that a ZIP archive is being piped into standard input, and it extracts the first member from the archive to stdout. If there is an argument, then the input comes from the specified file instead of from stdin. Unzipsfx is a modified version of unzip designed to be prepended to existing ZIP archives in order to form self-extracting archives. Instead of taking its first non-flag argument to be the zipfile(s) to be extracted, unzipsfx seeks itself under the name by which it was invoked and tests or extracts the contents of the appended archive.
