#!/bin/bash
for i in `seq -w 1 20`

user="user$i"
password=$(cat /dev/urandom | head -1 | md5sum | head -c 1-5)
useradd user$i
echo "$user:$password" | passwd --stdin $user
echo "$user-$password" >> userinfo.txt

- cat /dev/urandom | head -1 | md5sum | head -c 1-5 # 产生5位随机字母或数字
- useradd user # 添加用户命令
- echo "$user:$password" | passwd --stdin $user # 设置密码
