This article introduces the knowledge of "how to change the user name of the Ubuntu system". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

When we program in Linux, we sometimes find that the username is too long. Especially when the virtual machine small window is displayed, the front paths are added together one by one, and the result is that the path becomes very long. In this way, we have to change the line without tapping a few orders, which is very troublesome, so how to shorten the user name of Linux?

1. When we use usermod directly under the current user, we find that there are errors, as follows:

2. The error displayed is: user hujinjin is currently in use.

3. Log out the current hujinjin user, log in with another user, switch to root user, and then modify the user name, as shown below:

4. You can see that the modification was successful, but the folder name of my hjj user's home directory is still hujinjin and has not been changed to hjj.

We still don't have the effect we want. We try to rename the hujinjin folder to hjj. But the problem arises. Now we can't find the home directory of the hjj user, so we have to change the home directory of the hjj stored in the system from hujinjin to hjj.

Before modification, it is as follows:

5. After modification, it is as follows:

6. After the modification is completed, we switch to the hjj user under root, and find that we can switch to the user's home directory normally, as shown below:

7. Modification completed!
