linux命令行界面下如何防止错误格式化?(主要是防止弄混设备)
比如想格式化一个分区,结果却错误的对另一个分区进行格式化.
sdaX,只要敲错数字,就会出错.
如果是移动硬盘的话,编号还可能因为插入顺序不同而不同,更是加大错误格式化的可能性
有什么解决方法?

还是用 label 吧，给每个分区取个名字

这些貌似都是列出分区,mkfs的时候还是一不小心就打错了
3楼的label方法貌似不错,只要别重名就好.

不过,格式化的时候,能使用label进行?

比如这样：

mkfs.xfs /dev/disk/by-label/Erina

/dev/sda1 说白就是个文件嘛，2楼给出的路径就是个软链接，命令里面用软链接代替文件名就好了。

[自由建客]

fdisk -l
先看分区表，若是看分区表都无法辨别设备的话，你还是别用了。

分区差不多大小,文件系统也一样.
而且前后顺序也存在颠倒的可能
还是弄个相对固定的链接比较靠谱,也更简单.
2楼提供的链接貌似就是固定的
