Portability
–i Uses the CCITT standard cyclic redundancy check (CRC-CCITT). Data
communication network protocols often use a cyclic redundancy check to
ensure proper transmission. This algorithm is more likely to produce a
different sum for inputs—the only difference is byte order.
–p Uses the POSIX.2 checksum algorithm. This is the default.
–r Enables the use of an alternate checksum algorithm that has the advantage
of being sensitive to byte order.
–t Produces a line containing the total number of bytes of data read as well as
the checksum of the concatenation of the input files.
–T Enable autoconversion of tagged files.
cksum uses the following localization environment variables:
v LANG
v LC_ALL
v LC_CTYPE
v LC_MESSAGES

See Appendix F for more information.
