[FILE]...\n\n'cksum' prints the CRC checksum for each file along with the number\nof bytes in the file, and the file name unless no arguments were given.\n\n'cksum' is typically used to ensure that files transferred by\nunreliable means (e.g., netnews) have not been corrupted, by comparing\nthe 'cksum' output for the received files with the 'cksum' output for\nthe original files (typically given in the distribution).\n\nThe CRC algorithm is specified by the POSIX standard.  It is not\ncompatible with the BSD or System V 'sum' algorithms (see the previous\nsection); it is more robust.\n\nThe only options are '--help' and '--version'.  *Note Common\noptions::.\n\nAn exit status of zero indicates success, and a nonzero value\nindicates failure.\n"
