What is Nano?
Nano is a free, open-source text editor designed for Unix-like systems, including Linux. It is a clone of the older Pico editor, part of the Pine email client, but it is released under the GNU General Public License, making it widely accessible. Unlike more complex editors like Vim or Emacs, nano prioritizes simplicity, offering an intuitive interface with on-screen keybinding hints, making it ideal for quick edits or users new to the command line.
Nano is often pre-installed on many Linux distributions, such as Ubuntu, Debian, Fedora, and CentOS. Its small footprint and minimal dependencies make it a staple in lightweight environments, including servers and embedded systems.
