I don't want to build yet-another bashoneliners. I just want to write documentation that I find one-liners own mine own. Maybe, I can search in a search engine and find the optimal solution, but I want to solve these problems.
Also, this guide is written for me. So, I will not include your extra one-liners; however, we can fix and improve the usage and documentation for them.
There are a few thousand websites and tools, but I can recommend using www.man7.org.
