Be careful with that: > The shuf, shred, and sort commands sometimes need random data to do their work. For example, ‘sort -R’ must choose a hash function at random, and it needs random data to make this selection. > By default these commands use an internal pseudo-random generator initialized by a small amount of entropy, but can be directed to use an external source with the --random-source=file option. An error is reported if file does not contain enough bytes. -- https://www.gnu.org/software/coreutils/manual/html_node/Random-sources.html https://www.gnu.org/software/coreutils/manual/html_node/Rand... (emphasis mine) You might end up with a fairly easy-to-brute-force password using that method. They say "never roll your own crypto", but I think that advice probably holds pretty well for password generators(/managers). I'll stick with using a dedicated program. I reckon it's far less likely to have obvious blunders than something that's just been cobbled together using whatever tools happened to be lying around nearby.
