How to clean up a data file using AWK

How can I take the most of this video?

I encourage you to download the files used on the video so you will be able to try the same commands as me on your own system.

What is the target audience?

This video is clearly aimed toward new shell users. The video was designed on a Linux system and using the Bash shell. But the features demonstrated here are generic enough to work with other shells and/or other Unix-like OS (*BSD, MacOSX, …​).

What are the requirements?

  • You should have a working Unix-like system.

  • You should know how to open a terminal window.
