Random number generator Usage: random [ -c ] [ -b | -e[Digits] | -f[Digits] | -u[Bits] ] [ n ] random writes n pseudorandom values to stdout, where the values can be unsigned integers, floating point numbers between 0.0 and 1.0, or bytes of binary data. The default is one 31-bit unsigned integer. Default for floating point is 6 digits of precision, maximum is 17. random relies on the Win32 CryptGenRandom API in Windows as the underlying cryptographically secure pseudorandom number generator. Options: -c Continuously write random data until interrupted or until writes fail, e.g., if writing into a pipe that closes. -b Bytes of binary data. -e[Digits] E-format floating point. -f[Digits] Fixed point floating point. -u[Bits] Unsigned integers, maximum 64 bits. -h Help.
