批量添加用户和批量删除用户脚本

摘要: 考虑到大公司可能需要多个用户共同使用一台主机，因此管理上面可能不方便，因此批量添加用户，可以更好的管理用户。脚本亲测可行哦。本人英语不是太好，希望大家适当借阅。

#!/bin/bash
#The script is used to add a lot user.

#You want to add the name of user
echo -n -e "Please inout your name :"
read username

#The num of user
echo -n "Please input num:"
read num

#The users'name
n=1
while [ $n -le $num ]
do
useradd $username$n
n=`expr $n + 1`

done

#The users'password
echo -n -e "please input your passwd:"
read passwd

m=1
while [ $m -le $num ]
do
echo $passwd | passwd --stdin $username$m
m=`expr $m + 1`
done
#
