Get the current day

Whilst working on a variety of Bash scripts in your data analytics infrastructure, you find that you often need to get the current day of the week. You can see this is unnecessary duplication of code and can be refactored (reduce the size by writing more efficient code) using your new skills in Bash functions.

Write a simple Bash function that, when called, will simply print out the current day of the week. This will involve parsing the output of the date program from a shell-within-a-shell.

A reminder that the output of date will look something like this (depending on the timezone you are calling it from!)
