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
blkid -L | -Ublkid [-c ] [-ghlLv] [-o] [-s ][-t ] -[w ] [ ...]blkid -p [-s ] [-O ] [-S ][-o] ...blkid -i [-s ] [-o] ...
选项
-c <file> 指定cache文件(default: /etc/blkid.tab, /dev/null = none)-ddon't encode non-printing characters-h显示帮助信息-ggarbage collect the blkid cache-o <format> 指定输出格式-klist 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)-llook 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:-plow-level superblocks probing (bypass cache)-igather 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:
sudo blkid
2、显示指定设备 UUID:
sudo blkid -s UUID /dev/sda5
3、显示所有设备 UUID:
sudo blkid -s UUID
4、显示指定设备 LABEL:
sudo blkid -s LABEL /dev/sda5
5、显示所有设备 LABEL:
sudo blkid -s LABEL
6、显示所有设备文件系统:
sudo blkid -s TYPE
7、显示所有设备:
sudo blkid -o device
8、以列表方式查看详细信息:
sudo blkid -o list
