SYNOPSIS

       cksum [file . . . ]

DESCRIPTION

       Cksum  calculates  and  prints a checksum for each named file, and also
       prints the number of bytes in the file.  It is typically used  to  look
       for  bad  spots, or to validate a file communicated over some transmis-
       sion line.  The CRC used is based on the polynomial used for CRC  error
       checking in the ISO/IEC 8802-3:1992 Ethernet standard.

SEE ALSO

       sum(1), wc(1)

DIAGNOSTICS

       `Read  error'  is  indistinguishable  from end of file on most devices;
       check the block count.
