Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Sum is a core GNU utility written by Kayvan Aghaiepour and David MacKenzie and distributed with the UNIX- and Linux-based operating systems. This utility outputs the checksum of each argument file, as well as the number of blocks they take on disk. According to the manual page, sum uses two different algorithms for calculating the checksum and blocks, the SYSV checksum algorithm and the BSD checksum (default) algorithm. Switching between the two algorithms is done via command line options.
