done或者把脚本放到每个主机下面执行以下创建user脚本
#!/bin/bash
user_list=(hyh2 zhangsan2 lisi2)
group=dev4
for user in ${user_list[@]}
do
groupadd $group
echo "######组$group 创建完成#######"
useradd -g $group $user
echo "########用户$user 创建完成#######"
echo "${user}123"|passwd --stdin ${user}
echo "userpasswd 完成"
chmod u+w /etc/sudoers
sed -i "/^root/a\\${user} ALL=(ALL) NOPASSWD:ALL" /etc/sudoers
chmod u-w /etc/sudoers
