I need to know that in relation to a program that I tried to build: qpdf. During buildup it said that /dev/random or /dev/urandom were not available.
Thanks

So I got my answer.Using /dev/urandom or /dev/random
The character special files /dev/random and /dev/urandom provide an interface to the kernel's random number generator. You can use /dev/urandom as follows:Sample outputs:Code: Select all
$ od -vAn -N4 -tu4 < /dev/urandom
You can use /dev/random as follows:Code: Select all
2494028411
[/code]Code: Select all
$ od -An -N2 -i /dev/random Sample outputs: [code]62362
Code: Select all
echo $RANDOM
let x=( $RANDOM *42) && echo $x
