OverTheWire Wargames — Bandit

https://overthewire.org/wargames/bandit/

This one is an old favorite of mine. You start at level 0 and work your way up!

The next level’s information is provided once the previous level has been completed. For example, accessing Level 1 requires finishing Level 0 first.

All levels in the game have a corresponding page that can be accessed from the left-side menu.

You will be given the reference links to help you solve each level.

If you are stuck at any level, refer to the YouTube playlist below for solutions and explanations.

CMD Challenge

CMD Challenge is also a level-based online challenge. You start with a simple command printing hello world to the console, and challenges get trickier as you progress through levels. But fret not; if you are still trying to figure out what to answer at any stage, you can view solutions submitted by other users.

There are two other main challenges also. Each has its unique set of scenarios.

• 12 Days
• OOPS

Exercism

Exercism has various Community-sourced coding exercises for almost all mainstream programming languages, including BASH. Each language has a track that you can follow to complete the exercises.

Exercism has 90 different Bash exercises to help improve and hone your code-writing skills. You will discover new concepts and increase your proficiency through the levels.
