【shell脚本练习】批量添加用户和设置密码

题目

思路

user10+数字

脚本

#!/bin/bash
#addusers.sh

echo "-----add 9 users-----"
for i in {1..9}; do
username=user10$i
if useradd $username &> /dev/null; then
echo "$username"|passwd --stdin $username #脚本中通常这样比较容易修改用户密码
if [ $? -eq 0 ]; then
echo "add $username successful"
else
echo "$username added, change password failure "
fi
else
echo "add $username failure "
fi
done
