Error reading /home/user/.nano_history: Permission denied Press Enter to continue starting nano.
Sometimes when trying to edit a text file using "nano" we face a not so important but yes annoying error message saying that there is an error reading the file .nano_history from the current user home directory. Just by hitting the enter key it will proceed to the next step. But we want to fix this so the problem gets fixed so the next time we want to edit anything we don't face this kind of issue any more.
Error reading /home/user/.nano_history: Permission denied

Don't panic, the error has a quick fix.
Run as root or sudo the following command:
sudo chmod 755 /home/<username>/.nano_history
Put the correct password at the prompt, and you are done!
Nano is a gui less text editor, it is perfect for text editting when there is no X session active, or maybe when you can't start your X right.
Most used commands with nano:
CTRL+O - Saves the file you are editting. CTRL+K - Cuts the line where the cursor is. CTRL+W - Searches a string inside the text file. CTRL+T - Text correction CTRL+X - Quits after saving if not saved there will be a question.
