tldr

This is arguably one of the terminal tools that I use the most. The tldrcommand is a shorter, friendlier and better-looking version of the man command, containing only the most frequently used flags and options associated with the search term in question. For example, imagine that you want to learn more about the magick tool. You'd typically type man magick. But look at what happens when you type tldr magick instead:

tldr magick

For the sake of comparison, here's the traditional way:

man magick

Of course, man will continue to be the most solid reference. But tldr has surely helped me save a lot of time! More info on their website.
