From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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.

vim isn't required for any files, you just followed online tutorials for how to edit those files instead of RTFM

terminal text editing is convoluted because it has to strike a balance between figuring out when a keypress is part of the text you're typing, vs when it's a command you're using, and making sure that all the editor commands the designer wanted are accessible.

vim is great because it allows for thousands more editing commands and macros, and much more customization of the editor, up to allowing plugins that emulate other functionality. As it stands, my setup basically functions as a full, lightweight-ish, multi-language IDE that rivals Emacs or Visual Studio.

On top of all that, I don't have to move my hands away from the homerow of keys to navigate or edit, which may not seem like much, but adds up to a lot of avoid typos and time saved from moving my hands to reach the arrows/delete/home/end/pgup/pgdn.

Some examples:

h, j,k,l move left, down, up, and right respectively, but they can be combined with a number to move that many rows or columns; e.g. 6j will move down 6 rows

dd deletes a line, but using a number + d + a movement will delete that many characters/lines in the path of the cursor: e.g. 34dl will delete 34 characters to the right of the cursor, 12dk will delete 12 lines up.

gg will take you to the first line, G will take you to the last, and number + either will take you to that line: e.g. 3275gg or 3275G will take you to line 3275

and finally you can use /text or regex pattern you want to search for and Enter to search the document for the first occurence below your current location, and then use n to search for the next occurence, or N to search for the previous

That doesn't even scratch the surface (that's just the cheatsheet, which only scratches the surface), but if you can get a handle on only what I've said, and switching between input and command mode (i and Esc respectively), the speedup to navigation alone will make it seem more sensible.

And as always, don't forget to :wq (write to file and quit)
