How can file permissions be changed on a read-only file…

To modify the permission of a read-only file in Linux, you can use the chmod command to change the file’s permission. Here are the steps to modify the permission of a read-only file:

1. Open the terminal.
2. Navigate to the directory containing the read-only file using the cd command.
3. Use the following command to modify the file’s permissions: chmod +w filename. This will add write permission to the file.
4. Verify if the permissions of the file have been changed using the ls -l command. The permissions of a read-only file should include the “w” flag, indicating that write permission has been added.

Please note that changing the permissions of a read-only file may require administrator privileges or root user credentials. If you are not an administrator or root user, you may need to use the sudo command to execute the chmod command. For example, sudo chmod +w filename.

If you only want to remove the read-only permission from a read-only file without adding write permission, you can use the following command: chmod -w filename.
