Detailed steps for creating and deleting users under Linux

Linux under the user's operation is relatively easy to understand, the basic operation is as follows:

1. New Users

Only the root user can create a new user

[Plain] view plaincopy650) this.width=650; "src=" Https://code.csdn.net/assets/CODE_ico.png "width=" 12 " Height= "alt=" on code to view the chip "style=" Border:none; "/>650" this.width=650; "src=" Https://code.csdn.net/assets/ico _fork.svg "width=" height= "alt=" derived from My Code slice "style=" border:none; "/>

1. #useradd user1

When created, a user home directory with the same user name will be generated in the/I directory.
A new group is also created that has the same name as the user who belongs to the group.
If you want a new user to belong to a group that already exists, use the following command:

[Plain] view plaincopy650) this.width=650; "src=" Https://code.csdn.net/assets/CODE_ico.png "width=" 12 " Height= "alt=" on code to view the chip "style=" Border:none; "/>650" this.width=650; "src=" Https://code.csdn.net/assets/ico _fork.svg "width=" height= "alt=" derived from My Code slice "style=" border:none; "/>

1. #useradd-G Usergroup1 user1

The user is then part of the Usergroup1 group.
If you want it to belong to a group usergroup2 again, use:

[Plain] view plaincopy650) this.width=650; "src=" Https://code.csdn.net/assets/CODE_ico.png "width=" 12 " Height= "alt=" on code to view the chip "style=" Border:none; "/>650" this.width=650; "src=" Https://code.csdn.net/assets/ico _fork.svg "width=" height= "alt=" derived from My Code slice "style=" border:none; "/>

1. #useradd-G usergroup2 user1

Use the passwd command to set an initial password for the new user to log in:

[Plain] view plaincopy650) this.width=650; "src=" Https://code.csdn.net/assets/CODE_ico.png "width=" 12 " Height= "alt=" on code to view the chip "style=" Border:none; "/>650" this.width=650; "src=" Https://code.csdn.net/assets/ico _fork.svg "width=" height= "alt=" derived from My Code slice "style=" border:none; "/>

1. #passwd user1

2. Delete users

[Plain] view plaincopy650) this.width=650; "src=" Https://code.csdn.net/assets/CODE_ico.png "width=" 12 " Height= "alt=" on code to view the chip "style=" Border:none; "/>650" this.width=650; "src=" Https://code.csdn.net/assets/ico _fork.svg "width=" height= "alt=" derived from My Code slice "style=" border:none; "/>

1. Userdel < user name >

The files on the system are also deleted and can be used

[Plain] view plaincopy650) this.width=650; "src=" Https://code.csdn.net/assets/CODE_ico.png "width=" 12 " Height= "alt=" on code to view the chip "style=" Border:none; "/>650" this.width=650; "src=" Https://code.csdn.net/assets/ico _fork.svg "width=" height= "alt=" derived from My Code slice "style=" border:none; "/>

1. userdel-r User Name

3. New group

[Plain] view plaincopy650) this.width=650; "src=" Https://code.csdn.net/assets/CODE_ico.png "width=" 12 " Height= "alt=" on code to view the chip "style=" Border:none; "/>650" this.width=650; "src=" Https://code.csdn.net/assets/ico _fork.svg "width=" height= "alt=" derived from My Code slice "style=" border:none; "/>

1. groupadd< Group name >

4. Delete a group

[Plain] view plaincopy650) this.width=650; "src=" Https://code.csdn.net/assets/CODE_ico.png "width=" 12 " Height= "alt=" on code to view the chip "style=" Border:none; "/>650" this.width=650; "src=" Https://code.csdn.net/assets/ico _fork.svg "width=" height= "alt=" derived from My Code slice "style=" border:none; "/>
