LEARN ABOUT SUNOS
sum
sum(1B) SunOS/BSD Compatibility Package Commands sum(1B)NAME
sum - calculate a checksum for a file
SYNOPSIS
/usr/ucb/sum file...
DESCRIPTION
sum calculates and displays a 16-bit checksum for the named file and displays the size of the file in kilobytes. It is typically used to
look for bad spots, or to validate a file communicated over some transmission line. The checksum is calculated by an algorithm which may
yield different results on machines with 16-bit ints and machines with 32-bit ints, so it cannot always be used to validate that a file has
been transferred between machines with different-sized ints.
USAGE
See largefile(5) for the description of the behavior of sum when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
+-----------------------------+-----------------------------+
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |

|Availability |SUNWscpu |

SEE ALSO sum(1), wc(1), attributes(5), largefile(5)DIAGNOSTICS
Read error is indistinguishable from EOF on most devices; check the block count.
NOTES
sum and /usr/bin/sum (see sum(1)) return different checksums.
This utility is obsolete.
