NAME
+ +
+ + sum, md5sum, sha1sum – sum and count blocks in a file
+ +
+

SYNOPSIS
+ +
+ + sum [ −5r ] [ file ... ] +
+ + md5sum [ file ... ] +
+ + sha1sum [ file ... ]
+ +
+

DESCRIPTION
+ +
+ + By default, sum calculates and prints a 32-bit hexadecimal checksum, + a byte count, and the name of each file. The checksum is also + a function of the input length. If no files are given, the standard + input is summed. Other summing algorithms are available. The options + are
+ −r    Sum with the algorithm of System V’s sum −r and print the length + (in 1K blocks) of the input.
+ −5    Sum with System V’s default algorithm and print the length (in + 512-byte blocks) of the input. +
+ + Sum is typically used to look for bad spots, to validate a file + communicated over some transmission line or as a quick way to + determine if two files on different machines might be the same. + +
+ + Md5sum computes the 32 hex digit RSA Data Security, Inc. MD5 Message-Digest + Algorithm described in RFC1321. If no files are given, the standard + input is summed. +
+ + Sha1sum computes the 40 hex digit National Institute of Standards + and Technology SHA1 secure hash algorithm described in FIPS PUB + 180-1. If no files are given, the standard input is summed.
