Generate random numbers in bash

Posted on July 29, 2020

Easiest way is to use the $RANDOM variable.

>> echo "$RANDOM"

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
