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。
blkid -L | -U
blkid [-c ] [-ghlLv] [-o] [-s ][-t ] -[w ] [ ...]
blkid -p [-s ] [-O ] [-S ][-o] ...
blkid -i [-s ] [-o] ...
-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)
sudo blkid
sudo blkid -s uuID /dev/sda5
sudo blkid-s UUID
sudo blkid -s LABEL /dev/sda5
sudo blkid -S LABEL
sudo blkid -s TYPE
sudo blkid o device
sudo blkid o list
