When it comes to text editors in Linux, there are two major players which have famously been causing holy wars for at least a couple of hundred years now: Vi and Emacs. They are both extremely powerful, lightweight editors whose ages are a testament to how useful they have been and continue to be.
If you are already a Vi or Emacs user, then great! If you're not, and you do a lot of code editing under Linux, you should probably consider learning one of them. So, with that in mind, here's another text editor that you may or may not have heard about: GNU Nano.
GNU Nano is a basic command-line text editor which is installed by default with many Linux distributions. Nano is not intended to be anywhere near as feature-rich as Vi or Emacs. It is a very simple tool, but this means it requires little to no time investment to start using for basic file editing tasks. Nano's core commands are easy to learn because they're written out at the bottom of the screen, and files can be navigated intuitively with the cursor keys.
I find nano extremely handy, and it has some neat features that you may not have known about. In this post, I'd like to share some of nano's more hidden capabilities.
