Generate random numbers in bash

Posted on July 29, 2020
Easiest way is to use the $RANDOM variable.
>> echo "$RANDOM"
12261
Each time this parameter is referenced, a random integer between 0 and 32767 is generated.
A better way which I like is to use the GNU coreutil, shuf
One Random number between 69 & 420
shuf -i69-420 -n1
Five Random numbers between 69 & 420
shuf -i69-420 -n5
