批量创建100个系统用户，要求：帐号和密码(8位以上含数字和字母)均不能相同。

解答：

#!/bin/bash

for((i=1;i<101;i++))

do

printf -v num "%.4d" $i

userno=$num

##用户名username 是类似“user0001”“user0002”“user0003”这样的格式

username="user$userno"

##用户密码userpasswd 是类似“user-0001”“user-0002”“user-0003”这样的格式

userpasswd="user-$userno"

grep "^$username" /etc/passwd

##grep 查找后没有此用户 则会返回非0值

if [ $? -eq 0 ]; then

echo "$username exists!"

else

useradd -m "$tmpuser" -p "$userpasswd"

[ $? -eq 0 ] && echo "User '$username' has been added to system!" || echo "Failed to add a user!"

#!/bin/bash

......

再调用脚本 ./adduser.sh userlist 即可批量创建用户名与密码相同的用户。
