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

SYNOPSIS
     sum file

     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.
