DESCRIPTION     sum\b\b\b___
sums the contents of the bytes (mod 2^16) of
one or more files and prints the answer in octal.
A separate sum is printed for each file specified,
along with the number of whole or partial
512-byte blocks read.

In practice, sum\b\b\b___ is often used to verify that
all of a special file can be read without error.
