Command Line
youtube-dl is a small command-line program to download videos from YouTube and more than 1000 sites. It requires the Python interpreter and is therefore platform-independent.
It augmentable with front-ends such as Youtube-DLG. It can be integrated in other programs and so be used to watch online videos in local applications such as MPV.
The GitHub repository was shut down in October 2020. It was restored the following November. Meanwhile, youtube-dl was forked to youtube-dlc (a.k.a yt-dlc) during this time. The development of youtube-dlc was soon discontinued. But further youtube-dlc forked to yt-dlp.
The development of youtube-dl began in 2006 by rg3. rg3 withdrew in 2011 and the lead developer has changed.
Less is a free, open-source file pager. It can be found on most versions of Linux, Unix and Mac OS, as well as on many other operating systems.
jq is like sed for JSON data - you can use it to slice and filter and map and transform structured data with the same ease that sed, awk, grep and friends let you play with text.
jq is written in portable C, and it has zero runtime dependencies. You can download a single binary, scp it to a far away machine of the same type, and expect it to work.
jq can mangle the data format that you have into the one that you want with very little effort, and the program to do so is often shorter and simpler than you’d expect.

Comparison between htop and top
- In 'htop' you can scroll the list vertically and horizontally to see all processes and complete command lines.
- In 'top' you are subject to a delay for each unassigned key you press (especially annoying when multi-key escape sequences are triggered by accident).
- 'htop' starts faster ('top' seems to collect data for a while before displaying anything).
- In 'htop' you don't need to type the process number to kill a process, in 'top' you do.
- In 'htop' you don't need to type the process number or the priority value to renice a process, in 'top' you do.
- 'htop' supports mouse operation, 'top' doesn't
- 'top' is older, hence, more used and tested.
