What is the current behavior?

---

The common resource script was found not to properly work in cloud shell. Currently it only supports /dev/random which operates slightly different depending upon the OS implementation of /dev/random.

Issue: #7

What is the new behavior?

---

In attempts to make the script work properly multiple methods were introduced for creating the 3 digit unique string.

1. shuff
2. jot
3. /dev/random (bash or coreutils)

Does this introduce a breaking change?

• [NO]
