# sum(1)

    NAME
         sum - compute the checksum and block count of a file

    SYNOPSIS
         sum file

    EXAMPLES

         sum /user/ast/xyz   # Checksum /user/ast/xyz

    DESCRIPTION

         Sum computes the checksum of one or more files.  It is most often used to
         see  if  a  file copied from another machine has been correctly received.
         This program  works  best  when  both  machines  use  the  same  checksum
         algorithm.  See also crc.

    SEE ALSO
         cksum(1), crc(1).
