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.

Not powerful, but often useful, column -t aligns columns in all lines. EG

$ echo {a,bb,ccc}{5,10,9999,888} | xargs -n3
a5 a10 a9999
a888 bb5 bb10
bb9999 bb888 ccc5
ccc10 ccc9999 ccc888
$ echo {a,bb,ccc}{5,10,9999,888} | xargs -n3 | column -t
a5      a10      a9999
a888    bb5      bb10
bb9999  bb888    ccc5
ccc10   ccc9999  ccc888

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.
