blkid === 查看块设备的文件系统类型、LABEL、UUID等信息 ## 补充说明 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。要使用这个命令必须安装e2fsprogs软件包。 ### 语法 ```shell blkid -L | -U blkid [-c ] [-ghlLv] [-o] [-s ][-t ] -[w ] [ ...] blkid -p [-s ] [-O ] [-S ][-o] ... blkid -i [-s ] [-o] ... ``` ### 选项 ```shell -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) ``` ### 实例 1、列出当前系统中所有已挂载文件系统的类型: ```shell sudo blkid ``` 2、显示指定设备 UUID: ```shell sudo blkid -s UUID /dev/sda5 ``` 3、显示所有设备 UUID: ```shell sudo blkid -s UUID ``` 4、显示指定设备 LABEL: ```shell sudo blkid -s LABEL /dev/sda5 ``` 5、显示所有设备 LABEL: ```shell sudo blkid -s LABEL ``` 6、显示所有设备文件系统: ```shell sudo blkid -s TYPE ``` 7、显示所有设备: ```shell sudo blkid -o device ``` 8、以列表方式查看详细信息: ```shell sudo blkid -o list ```
