The Nano Editor is a free, open-source text editor for Unix and Linux systems. It is licensed under the GNU General Public License (GPL). The Nano Editor is a popular choice for many users because it is easy to use and has a simple interface. The Nano Editor has many features that make it a powerful text editor, such as syntax highlighting, search and replace, spell check, and more. While working with nano, you may accidentally press anything, and your text gets deleted, and you need those lines again. The Nano Undo command is the best option in this case. It will help you retrieve those lines the moment you have deleted them.
How to Undo in Nano Editor? [Nano Undo Command]
You can use the following shortcut keys to undo in nano:
Alt + U is used to undo anything in the nano editor.
Alt + E is used to redo anything in the nano editor.
Finally, if you want to exit Nano without saving any changes, you can use the Ctrl+X shortcut. This will prompt you to confirm your decision before exiting Nano.
In Nano, undoing is just as easy as doing. All you have to do is press Alt+U, and your last action will be undone. If you make a mistake and need to undo multiple actions, you can keep pressing Ctrl+U until you've undone everything you want. It's that simple! So next time you're in Nano and make a mistake, don't panic — just press ALT +U and carry on. But remember, once you save your file, you cannot undo it again and retrieve the lines back. So before saving, if you need to retrieve the lines back, use the undo option.
