When logging in to a new user in a Linux system, the shell starts with $, and the user name and path are not displayed.

Problem description: In the Linux system, after using the useradd command to create a new user, when logging in to the user, the shell starts with $, and the user name and path are not displayed, as follows:

$
$
$

 Solution: After viewing the /etc/passwd file, it is found that the newly created user does not specify a shell. We just need to specify it as /bin/bash.

1. Switch to root user
2. Use the usermod command to modify the shell type

$su
$
root@VM-202-164-ubuntu:/app# usermod -s /bin/bash du
root@VM-202-164-ubuntu:/app#

 Successfully solved!

 

If it is not resolved, please try the following methods (excerpted from other people's methods, failed to try):

1. Add the following code to ~/.bash_profile, if there is no such file, you can create it yourself:

   you ~ / .bash_profile
   #join in
   #export PS1='[u@h W]$'
   #keep

    
2. Make the variable take effect:

   source ~/.bash_profile

    
3. re-register
