`cksum': Print CRC checksum and byte counts =========================================== `cksum' computes a cyclic redundancy check (CRC) checksum for each given FILE, or standard input if none are given or for a FILE of `-'. Synopsis: cksum [OPTION]... [FILE]... `cksum' prints the CRC checksum for each file along with the number of bytes in the file, and the filename unless no arguments were given. `cksum' is typically used to ensure that files transferred by unreliable means (e.g., netnews) have not been corrupted, by comparing the `cksum' output for the received files with the `cksum' output for the original files (typically given in the distribution). The CRC algorithm is specified by the POSIX.2 standard. It is not compatible with the BSD or System V `sum' algorithms (see the previous section); it is more robust. The only options are `--help' and `--version'. Note: Common options.
