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.
zoxide. It's a fabulous cd replacement. It builds a database as you navigate your filesystem. Once you've navigated to a directory, instead of having to type cd /super/long/directory/path, you can type zoxide path and it'll take you right to /super/long/directory/path.
I have it aliased to zd. I love it and install it on every system
You can do things like using a partial directory name and it'll jump you to the closest match in the database. So zoxide pa would take you to /super/long/directory/path.
And you can do partial paths. Say you've got two directories named data in your filesystem.
One at /super/long/directory/path1/data
And the other at /super/long/directory/path2/data
You can do zoxide path2 data and you'll go to /super/long/directory/path2/data
