The classical introductory exercise. Just say "Hello, World!".

"Hello, World!" is the traditional first program for beginning programming in a new language or environment.

The objectives are simple:

  • Modify the provided code so that it produces the string "Hello, World!".
  • Run the test suite and make sure that it succeeds.
  • Submit your solution and check it at the website.

If everything goes well, you will be ready to fetch your first real exercise.

Welcome to Bash!

Unlike many other languages here, bash is a bit of a special snowflake. If you are on a Mac or other unix-y platform, you almost definitely already have bash. In fact, anything you type into the terminal is likely going through bash.

The downside to this is that there isn't much of a development ecosystem around bash like there is for other languages, and there are multiple versions of bash that can be frustratingly incompatible. Luckily we shouldn't hit those differences for these basic examples, and if you can get the tests to pass on your machine, we are doing great.


Please follow these instructions to install bash on your system.
