Nano Text Editor is a command line utility to create files. It was the first release in 1999 to replace the older Pico Editor. To make it available for everyone, Nano was published under a free & open source license, hence widely used in both Unix and Linux-based systems.
Like VIM, Nano is also a lightweight text editor but offers a user-friendly interface, so that even beginners can easily use it. As there is no graphical user interface, Nano is a good option to use not only on Desktop but even on Linux servers where CLI is used to edit scripts, configuration files, and other available text-based files.
The minimalistic interface of Nano displays only the most important information, such as the filename, line number, and cursor position. This makes it easy to navigate through text files and edit them quickly.
Furthermore, operating Nano is also easy with the help of various keyboard shortcuts. For example, to save the file after editing user can use the Ctrl+O shortcut; in a similar way Ctrl+X can be used to exit the editor; whereas to cut the current line use Ctrl+K and Ctrl+U to uncut the previously cut line.
Apart from basic editing it also supports advanced features like syntax highlighting, auto-indentation, regular expression search and replace multiple buffers, and macros. These features make it a powerful tool for editing and manipulating text files.
