How to create a file without permission in Linux

If you do not have the permission, you should use commands to solve the problem. In Linux, there are super users (Root) and common users. Normal users cannot directly operate directories without the permission.

There are two solutions:

Open the terminal: Alt + F2, enter gnome-terminal, and press Enter. On the displayed page, perform the following operations:

1. Enter sudo Nautilus and press Enter. Enter your user password. In this way, a resource manager with Super User Permissions is opened. Then you can directly create your directory.
2. Run the command to create your directory. First, run CD to the address of the directory you want to create, such as CD/OPT. Then run the sudo mkdir directory name and enter the user password as prompted.
