标识OS Parition驻留的磁盘(用于脚本)？
标识OS Parition驻留的磁盘(用于脚本)？
提问于 2021-07-07 00:56:44
我试图自动识别操作系统驻留在哪个磁盘(而不是分区)上，该程序将格式化多个附加磁盘(因此它不会意外地格式化OS磁盘)。
我目前使用的是dmidecode -s system-uuid，但我认为这给出了定义UUID。
我可以向用户询问，但这将是一个麻烦。
是否有任何方法可以识别以脚本格式可用的磁盘(如/dev/sdX)和UUID？
如果它生成准确的结果，如:运行CODE_HERE，并获得结果/dev/sdX，那么更好的是:)

您可以尝试stat / -或其格式化版本。
输出将类似于
File: /
Size: 4096 Blocks: 8 IO Block: 4096 directory
Device: 10302h/66306d Inode: 2 Links: 19
Access: (0755/drwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root)
[...]设备信息:- 10302的十六进制可以解码为103 h= 259十进制(一个nvme设备)和02h =分区2。
lsblk确认了这一点(以十进制为单位)
nvme0n1 259:0 0 238.5G 0 disk
├─nvme0n1p1 259:1 0 260M 0 part /boot/efi
├─nvme0n1p2 259:2 0 48.8G 0 part /
└─nvme0n1p3 259:3 0 48.8G 0 part /mnt/linux应该可以从这两个命令获得更好的脚本友好输出。
blkid可用于获取分区UUID。
