Nano is the most fundamental, command-line-based text editor for Linux. It has all common text editor features, including highlighting syntaxes, multiple buffers, scanning and replacement with regular expression support, type corrections, and UTF-8 encoding. You can easily save and exit in the nano editor through the command-line options given in this tutorial.
How to Save and Exit Nano
- Save Nano Command: Ctrl+O will save the modifications you've made to the file. When you save the file, it will be generated if it does not already exist.
- Exit Nano Command: Ctrl+X will close nano. If any patches haven't been saved yet into your system, you'll be prompted to do so.
You must have the write permissions on the file to save it. You must have written permission to the directory where the file would be generated while making a new file in the nano editor to save the file.
