On a Linux system, when you create a new user with the Useradd command, the shell starts with $ when you log on to the user, and the user name and path are not displayed, as follows:

1. Add the following code to the ~/.bash_profile, if none of the files can be created by yourself: Java code
   1. VI ~/.bash_profile
   2. #加入
   3. #export ps1=' [[email protected] w]$ '
   4. Uppercase W represents the last path, and lowercase w for detailed path
   5. #保存
2. Make variables effective: Java code
   1. SOURCE ~/.bash_profile
3. Re-Login
