There are many shells available for Linux, arguably the most popular is 'bash' which stands for the Bourne-Again SHell. The shell you will be developing for this lab will work similarly to 'bash' but will have fewer features.

Before you start, it might be helpful to read the 'man' pages for these system calls.
