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.
Helix is a terminal based text editor. It’s much like vim / neovim, but unlike those editors it’s good to go right out of the box, no configuration or plugins needed to make it work well.
Topgrade is one I haven’t used, but it looks like its intended purpose is to let you upgrade your apps with one command, even if you use multiple different package managers (I.e. if you were on Ubuntu, you could use it to upgrade your apt packages, at the same time as your snap packages, as well as flatpak, nix, and homebrew if you’ve added those.)
Fish is a replacement of bash that’s a bit more user friendly (has some cool auto completion features out of the box and more sane behaviour like handling of spaces when expanding variables). I personally started to use nutshell recently but unlike fish it’s very different from bash.
Starship is a “prompt” for various shells (that bit of text in terminal before you enter the command that shows current user and directory in bash). I haven’t used it but AFAIK it has many features like showing current time, integration with git, etc.
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.
