cksum(C)
cksum --
write file checksums and sizes
Syntax
cksum [ file ... ]
Description
cksum calculates and prints a cyclic redundant check
(CRC) for each input file, and also prints the number of
bytes in each file.
If no file is named, standard input is used.
cksum is usually used to quickly compare a suspect copy of
a file against a trusted version of the same file.
Exit values
cksum returns the following values:
0-
all files were processed successfully
>0-
an error occurred
Notes
The CRC used is based on the polynomial used for
CRC error checking in the networking standard
ISO 8802-3 {B7}.
