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.
batcat
It’s like cat but better. Great for when you just want to look at the contents of a file, without loading a whole text editor.
Oh also, tldr
My procedure for learning how to use a cli command goes tldr page -> --help if the tldr fails to help me -> THEN the full manpage
I like batcat aka bat, but nominate the humble ‘cat’ instead.
Want to copy a disk image to a device? You can use cat for that:
cat file.iso>/dev/sdf
What to copy local stdout over ssh? Use cat.
ls -l | ssh myhost 'cat >out.txt'
That’s simple and surprisingly powerful.
