Everything about https://overthewire.org/wargames/ was lovely from the 90s style hyperlink search that lead me to the site, to the website’s nostalgic and somewhat dated CSS. The site is a monument to people doing good, it still amazes me that people want to and are motivated enough to put together something this comprehensive purely for others to play and learn.
The site teaches you the bash command line through a series of games that give you everything you need to know to master it. The site is designed so that it does not just teach you the basic syntax but you learn why commands exist and how they interact with each other. Moreover the lessons help you understand the command lines place in the system and how it allows you to manipulate / navigate it.
The first game is a series of challenges that gets you to find hidden passwords. In each level you are on a remote system and to unlock the next location you have to find the password. Its basically an escape room but without walls. Navigating the remote file system really does make you feel like a hacker! I highly recommend this to anyone who wants to know more about Linux based systems and bash.
