How can I use /dev/(u)random on Ubuntu or any *nix sistems ?
I searched at google but I can't find how to :(
I tried this but it says permission denied.
Note : I also tried as root.
/dev/(u)random sudo /dev/(u)random sudo -s;/dev/(u)random
It's a file like device, so you can do things like cat it or copy from it. For instance:
Creates a file containing 4K of random bytes.
Will continue to write random bytes to that file until you hit Ctrl-C. Don't do this on a low performing system...
Will write 30 lines of random bytes
