cubehash 1 user commands redo cubehash checksum utility cubehash filename(s) cubehash prints the CubeHash content hash values of each filename named. The output format is modelled on that of sha2561. The old program that used to go by this name is now redo-info1. cubehash tries not to hash the same file multiple times. If the same filename argument is supplied multiple times, or if by comparing device and i-node numbers it transpires that cubehash has already hashed the file, it prints out the prior hash value without re‐reading the file.
