In the last 18 months, the author, Robert Elder, has created 108 YouTube videos summarizing commands in the GNU Coreutils Package. These videos offer a quick reference and examples on how to use each command. The Coreutils package is essential for basic tasks on GNU/Linux systems and reflects historical significance dating back 60 years. Some commands have surprising, rich histories, like ‘pinky’ based on the notable ‘finger’ command. The author also explores the financial aspects and personal growth gained from creating these videos. Additionally, readers can join the author’s mailing list for free software and engineering content.
