How to resolve the issue of not being able to exit the vi editor in Linux when pressing ESC key?

If you are unable to exit the Vi editor by pressing the Esc key in Linux, it could be due to some issues with Vi editor or incorrect configuration files. Here are some possible solutions:

1. Check for any misconfigurations: you can try reloading Vi’s configuration file. Enter the following command in the terminal:

source ~/.vimrc

perhaps

source /etc/vim/vimrc

This will reload the configuration file and may resolve the issue.

1. Forced Exit: If you are unable to exit Vi normally, you can try using the forced exit command. Press Ctrl+C or Ctrl+Z in the terminal to forcefully terminate the Vi editor.
2. Try using a different editor: If the issue cannot be resolved, you can try using alternative text editors such as Nano or Emacs instead of Vi editor.
3. To reinstall Vi: If the issue persists, consider reinstalling the Vi editor. Input the following command in the terminal:

sudo apt-get remove vim
sudo apt-get install vim

This will uninstall and reinstall the Vi editor, which may help solve the issue.

If the above methods are not able to solve the problem, further examination of system configuration or seeking assistance from professional personnel may be necessary.
