cksum

Print CRC checksum and byte counts

Computes a cyclic redundancy check (CRC) checksum for each given FILE, or standard input if none are given or for a FILE of `-'.

SYNTAX
      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; it is more robust.

   The only options are `--help' and `--version'.
