How to restore read-only files in Linux

First we open the operating system.

Find the terminal window in the menu bar and click to enter.

We create a new file as an example and set it as a read-only file.

If a read-only file is opened, read-only will be displayed.

chmod 666 test.txt. At this time, execute the command. The test file is test.txt. 666 means to change it to a readable and writable file.

No prompt will be displayed when opening the file at this time. Belongs to normal mode.

chmod 222 test.txt is a file that is made writable but unreadable.
