     • The prompt is displayed again each time a command has been executed.
     • The command lines are simple, no semicolons, no pipes, no redirections or any other advanced features.
     • The command lines are made only of one word. No arguments will be passed to programs.
     • If an executable cannot be found, print an error message and display the prompt again.
     • Handle errors.

     • Implement the env built-in, that prints the current environment
8. What happens when you type ls-l in the shell - blogpost
   • Write a blog post describing step by step what happens when you type ls -l and hit Enter in a shell. Try to explain every step you know of, going in as much details as you can, give examples and draw diagrams when needed. You should merge your previous knowledge of the shell with the specifics of how it works under the hoods (including syscalls).
