Nano is the command-line text editor of choice for many Linux users, particularly those on Ubuntu, partially because its basic functions are quite intuitive to use.
Even so, there are a few things that trip new users up. We've already covered how to exit nano and Linux base 64 decoding, but today's topic is deleting a line in nano. This quick guide will cover:
- Deleting a line in nano
- How to delete multiple lines in nano
- How to select all and delete in nano
- How to undo deleted text
- Troubleshooting and common issues

Deleting a line in nano
Though it makes copious use of hotkeys, deleting a line in nano isn't that difficult. Here's the step-by-step process:
Step 1: Open the file
In Terminal, open the file you want to edit with:
nano yourfilename.txtStep 2: Navigate to the line you want to delete
You can do this using the arrow keys to move line-by-line downwards. Alternatively, you can use the nano go to line function by typing Ctrl + Shift + _ and entering the line number. You don't need to be at the end of the line for this to work.
Step 3: Use the delete shortcut
Press Ctrl + K to cut the text and therefore delete the line in nano
That's it! You can now delete the empty space with a backspace if you wish, or delete other parts of your document.
Nano: Delete multiple lines with delete selection
If you want to delete many lines in a document, going through and pressing Ctrl + K on each is tedious. If you want to use nano to delete multiple lines, use its selection tools first.
Step 1: Open the file
To open the file you'd like to modify, type nano filename.txt in your terminal. You'll see nano's interactive editor.
Step 2: Move to the first line you want to select
Using your arrow keys, navigate to the first line of the block you'd like to select. You don't need to be at the end of the line.
Step 3: Set your mark and select
Press the Meta key (Alt/Command) + A to set your mark. Use the arrow keys to move up or down the document, with each line selected along the way.
Step 4: Delete the text
You can now delete the multiple lines selected in nano by pressing Ctrl + K and save and exit nano.
How to select all and delete in nano
Deleting all contents of a file in nano is much easier than some guides would have you think. Rather than messing around with selections, you can use the nano clear file shortcut.
Step 1: Open the file in nano
In Terminal, open the file you want to edit with:
nano filename.txtStep 2: Press the "clear file" shortcut
With your cursor in its starting position at the beginning of the document, you can press Alt + T to delete all text in nano.
Note: If you're already midway down the document, you can use Alt + \ to quickly return to the beginning.
How to undo deleted text in nano
It's quite easy to make mistakes when deleting text with nano, but don't worry. While your usual Ctrl + Z won't work, there's another hotkey.
To recover deleted text in nano, press Alt + U to undo.
Troubleshooting and common issues
Ctrl + K isn't working in my terminal
This is usually because your terminal software, such as the VS Code terminal, is intercepting the key combination for its own shortcut. Try with a different terminal if possible, and if that works, check your original terminal's configuration files to rebind the relevant shortcut.
Nano editor disappeared and left a lock file
An easy mistake to make. Ctrl + Z in nano suspends the editor rather than undoing, but does not exit the process. As a result, users see a warning when they try to nano back in. The fix is to type fg to bring your active nano session back to the foreground.
My server/PC crashed, and now my file is stuck being edited
You can usually override this by just typing "Y" when asked if you still want to edit the document. However, if you're using the -G flag or have set locking enabled in your .nanorc file, you need to delete the .lock file associated with your document if you want to continue. To do so:
- Run
lsin your file's directory - Look for a file like
.yourdocument.ext.swp - Run
rm -f .yourdocument.ext.swp
You should now be able to edit your document as normal.

FAQs
How do I delete a line in Nano using PuTTY?
The same shortcuts apply in PuTTy as in nano — press Ctrl + K to delete a line. That said, PuTTY can sometimes intercept certain key combinations. If Alt + A won't set a mark, try pressing Esc then A instead, since PuTTY treats Esc followed by a key as the Meta/Alt equivalent.
How do I delete a Line in Nano using bash-cli?
If you need to delete certain lines using bash rather than interactively, you can use sed. For example, sed -i '5d' yourfilename.txt would delete line 5 from your file. Alternatively, you could delete a range with something like sed -i '3,7d' yourfilename.txt.
How can I display line numbers in nano?
Use the -l flag when opening a file, for example nano -l yourfilename.txt. Or, if you already have the file open, press Alt + N.
If you don't want to do this every time, you can add set linenumbers to your ~/.nanorc file.
How can I move to the end of the line in nano?
Press Ctrl + E or use the arrow keys to move your cursor. You can use Ctrl + A to jump back to the front of the line.
