Which Linux tool or command is surprisingly simple, powerful, and yet underrated?"
Which Linux command or utility is simple, powerful, and surprisingly unknown to many people or used less often?
This could be a command or a piece of software or an application.
For example I'm surprised to find that many people are unaware of Caddy, a very simple web server that can make setting up a reverse proxy incredibly easy.
Another example is fzf. Many people overlook this, a fast command-line fuzzy finder. It’s versatile for searching files, directories, or even shell history with minimal effort.
degit is a tool that will check out a git repo (or a specific branch or commit), but not set it up as a git repo. Basically just downloading a specific commit to a directory.
Can single-branch handle cloning from a particular commit? I know that it's possible to clone particular branches and particular tags with depth=1, but OP states cloning at a particular commit, not HEAD.
