磁盘配额管理实战，首先使用脚本创建五个用户，全部属于一个用户组，并且设置统一的密码。
[root@liguo110 sifangcai]# vim addaccout.sh
#!/bin/bash
groupadd myquotagrp #增加myquotagrp组
for username in myquota1 myquota2 myquota3 myquota4 myquota5 #循环设置五个用户
do
useradd -g myquotagrp $username #将五个用户加入用户组
echo "password" | passwd --stdin $username
done
mkdir /home/myquota
chgrp myquotagrp /home/myquota
chmod 2770 /home/myquota #设置目录权限为2770
[root@liguo110 sifangcai]# sh addaccout.sh
