Show only after a new Linux user, $ switch problem

1, execute the following command to create a new user

useradd -d /home/sam -m sam -s /bin/sh -g group -G adm,root

This command specifies the user's login shell is / bin / sh

This is why the problems described in the title

 

2, need to be performed under root privileges:

vim /etc/passwd

 

 The sam figure above the line of '/ bin / sh' modified '/ bin / bash'

Then save enough!
