Introducing "vim sudo write" for programmers

If you're a programmer using Linux or Unix as your operating system, chances are you've faced the dreaded "permission denied" error when trying to save changes to a file owned by the administrator. This is where "vim sudo write" comes in handy.

What is vim sudo write?

"vim sudo write" is a command that allows you to write changes to a file that requires root access, without having to switch to the root user. It combines the power of vim editor and the elevated privileges of the sudo command, saving you time and effort.

How to use vim sudo write?

Using "vim sudo write" is simple. First, open the file you want to edit with vim editor:

vim filename.ext

Then, when you try to save the changes, use the following command:

:w !sudo tee %

This will prompt you for your sudo password, and then write the changes to the file as the root user.

Why use vim sudo write?

Without "vim sudo write", you would need to save the file as a temporary file, switch to the root user, copy the temporary file to the original file, and delete the temporary file. This can be time-consuming and prone to errors.

With "vim sudo write", you can save changes to the original file directly, without leaving vim editor. This saves time and minimizes the risk of making mistakes.

Conclusion

If you're a programmer who frequently works with root-owned files, "vim sudo write" is a useful tool to add to your arsenal. It simplifies the process of editing files that require root access, and saves you time and effort. Give it a try and see if it works for you!
