sort -R file
-R, --random-sort(sort by random hash of keys)
It simply hashes the input keys then sorts on that hash value.
The choice of hash function is a random one, usually based on a simple internal pseudo-random number generator but you can change the source of this randomness by using the
--random-source=FSPECoption.This will use
FSPECas the source of randomness for selecting the hash information, typically/dev/randomor its kin.
