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.

    Yep, here’s my Starship prompt, for example:

    So, I have it configured to show:

    • the exit code of the last command (if it’s non-zero),
    • the duration of the last command (if it’s longer than 2 seconds),
    • the time (when the last command ended),
    • the current directory,
    • the current Git branch, and it also shows some Git status information, for example the $ means I have something stashed,
    • and finally the technology in use in a repository/directory, so in this case that repo uses Rust and the compiler version is 1.83.

        Nope, I’m glad to share.

        I personalized it from the “Gruvbox Rainbow” preset from here: https://starship.rs/presets/
        So, you might prefer that, if you’re not, well, me.

        You will need to set up a NerdFont, like the Starship installation guide says.

        Here’s my configuration:

        Oh, when you’re coding something in a Git repo and you realize that you need to make a different change before you continue coding (e.g. switch to a branch, pull newest changes, or just create a separate smaller commit for part of your change), then you can run git stash push to put away your current changes, then make your other change, and then run git stash pop to bring your ongoing changes back. I recommend reading git stash --help, if you want to use it.

        Sometimes, though, you might end up just taking it into a different direction altogether or simply forget that you had something stashed. That’s when that indicator comes in handy. Because while you can have multiple things stashed, I do find it’s best not to keep them around for too long. If you do want to keep them for longer, then you can always create a branch and commit it as WIP onto there, so that you can push it onto a remote repo.
