- NAME
- cksum - checksum and count the bytes in a file
-
- SYNOPSIS
- cksum [--help] [--version] [file...]
-
- DESCRIPTION
- This manual page documents the GNU version of cksum.
- cksum computes a cyclic redundancy check (CRC) for each
- named file, or the standard input if none are given or
- when a file named `-' is given. It prints the CRC for
- each file along with the number of bytes in the file, and
- the file name unless no arguments were given.
-
- cksum is typically used to make sure that files have been
- transferred by unreliable means (such as netnews) have not
- been corrupted, by comparing the cksum output for the
- received files with the cksum output for the original
- files. The CRC algorithm is specified by the POSIX.2
- standard. It is not compatible with the BSD or System V
- sum programs; it is more robust.
-
- --help Print a usage message and exit with a non-zero sta-
- tus.
-
- --version
- Print version information on standard error then
- exit.
