Linux Bulk Create user and bulk delete users

The following is a batch creation of users:

#首先我们需要创建一个xxx. txt file, write the user we created in this text, and note that each user needs to be wrapped.

Vim User.txt

User1

User2

User3

#创建一个xxx the. Sh shell script, and then use the For loop to iterate through the created User.txt, which is the shell script:

#!/bin/bash

#我这里是把shell脚本和txt文件创建在同一个目录下, if you are not in the same directory, be aware of the following path

For the user in ' Cat user.txt '

Do

Useradd $user

#这里的passwd--stdin means: Non-interactive, direct input password

echo "123" | passwd--stdin $user

echo "The User Useradd success!"

Done

The following is a bulk delete user

#看了以上的批量创建用户, then it's easy for the next batch to delete the user!

#原理基本上是一样的, it's just a different order, I don't have much to explain.

#以下是shell脚本

#!/bin/bash

For the user in ' Cat user.txt '

Do

Userdel-r $user

echo "The User deletc success!"

Done
