# Blkid 查看磁盘 ID
|
|||
|
|
|
|||
|
|
在Linux下可以使用blkid命令对查询设备上所采用文件系统类型进行查询。blkid主要用来对系统的块设备（包括交换分区）所使用的文件系统类型、LABEL、UUID等信息进行查询。
|
|||
|
|
|
|||
|
|
命令选项如下：
|
|||
|
|
|
|||
|
|
```sh
|
|||
|
|
-c <file> 指定cache文件(default: /etc/blkid.tab, /dev/null = none)
|
|||
|
|
-d don't encode non-printing characters
|
|||
|
|
-h 显示帮助信息
|
|||
|
|
-g garbage collect the blkid cache
|
|||
|
|
-o <format> 指定输出格式
|
|||
|
|
-k list all known filesystems/RAIDs and exit
|
|||
|
|
-s <tag> 显示指定信息，默认显示所有信息
|
|||
|
|
-t <token> find device with a specific token (NAME=value pair)
|
|||
|
|
-l look up only first device with token specified by -t
|
|||
|
|
-L <label> convert LABEL to device name
|
|||
|
|
-U <uuid> convert UUID to device name
|
|||
|
|
-v 显示版本信息
|
|||
|
|
-w <file> write cache to different file (/dev/null = no write)
|
|||
|
|
<dev> specify device(s) to probe (default: all devices)
|
|||
|
|
Low-level probing options:
|
|||
|
|
-p low-level superblocks probing (bypass cache)
|
|||
|
|
-i gather information about I/O limits
|
|||
|
|
-S <size> overwrite device size
|
|||
|
|
-O <offset> probe at the given offset
|
|||
|
|
-u <list> filter by "usage" (e.g. -u filesystem,raid)
|
|||
|
|
-n <list> filter by filesystem type (e.g. -n vfat,ext3)
|
|||
|
|
```
