Detailed steps for creating and Deleting Users in linux
In linux, user operations are relatively easy to understand. The basic operations are as follows: 1. Only root users can create new users.

# Useradd user1

A user home directory with the same user name is generated in the/home directory.
A new group is created, which has the same name as this user and belongs to this group.
To assign a new user to an existing group, run the following command:

# Useradd-g usergroup1 user1

In this way, the user is a member of usergroup1.
If you want to make it belong to another group of usergroup2, use:

# Useradd-G usergroup2 user1

Use the passwd command to set an initial password for new users to log on:

# Passwd user1

2. delete a user

Userdel <User Name>

Delete files from the system. You can use

Userdel-r user name

3. Add a group

Groupadd <Group Name>

4. delete a group

Groupdel <Group Name>

The end...
