[SHELL脚本练习]自动分区格式化挂载磁盘

共计 1828 个字符，预计需要花费 5 分钟才能阅读完成。

脚本用途

主要用于阿里云批量开通Linux服务器后的数据盘挂载处理

脚本功能

1、自动分区格式化并挂载磁盘

2、多磁盘可自动重复识别操作

3、对已挂载硬盘过滤处理，不会影响

4、仅学习shell测试编写23333333

脚本测试截图

已准备三块未挂载磁盘用于测试

单块磁盘依次挂载执行

挂载磁盘TEST-1前执行

挂载TEST-1磁盘，并执行

挂载TEST-2前执行

挂载TEST-2后执行

挂载TEST-3前执行

挂载TEST-3后执行

依次挂载结果

多磁盘同时挂载
