  Linux create and delete user step
     
  Add Date : 2017-08-31      
         
         
         
  Linux user operations is relatively easy to understand, the basic operation is as follows:

1, the new user

Only the root user can create a new user

#useradd user1

It will generate a user with the same name in the user's home directory / home directory after New.
At the same time will create a new group, the group with the same name as the user, the user is a member of the group.
If you let the new user belongs to a group that already exists, use the following command:

#useradd -g usergroup1 user1

So that the user belongs to a group of usergroup1.
If you want it to be part of a group usergroup2, then you use:

#useradd -G usergroup2 user1

Use the passwd command to set an initial password, a new user can log in:

#passwd user1

2, delete users

userdel < username >

The files on the system are removed, you can use

userdel-r username

3, the new group

groupadd < group name >

4. Delete Group

groupdel < group name >

The end ...
