How to change $ to # in Linux

In this system, the # sign represents the root user and the $ sign represents the ordinary user. So how do you make them switch quickly?

1. Turn on the computer system first, then click the launcher.

2. There is software installed in the launcher. Just find the terminal software and click it to start it.

3. Or you can right-click and select Open terminal here, which can also achieve the purpose of quickly opening the terminal.

4. After opening, you will see a $ symbol. Enter su and then enter your administrator password. This time it will become #.

5. If you want to exit #, then enter: exit

At this time, it will recover from # back to $.

6. Of course, for some distributions, you need to set the root password before you can open the switch. If the above method cannot switch, you should first enter: sudo passwd root

After pressing Enter, enter your current user's password, then enter a new password for root. Enter it twice and it's done. Then you can use the above su to switch to the root user.
