1.　lsblk -f

这个命令是查看系统可以识别出的所有分区的文件系统类型

2.　blkid

查看已格式化分区的 UUID 和文件系统。使用 blkid 可以输出分区或分区的文件系统类型，查看 TYPE 字段输出。

/dev/mapper/centos-root: UUID="dac3b400-0af5-43c6-9bd9-a7867bfb3051" TYPE="xfs" 
/dev/sda2: UUID="CY71gX-G43e-taNL-1XFc-LyU1-939X-iqPF1t" TYPE="LVM2_member" 
/dev/nvme0n1p1: UUID="93f8545f-8fef-4f33-ad13-419baba99a54" TYPE="ext3" 
/dev/sda1: UUID="d296d532-3b6f-4356-97d5-8eea439d3187" TYPE="xfs" 
/dev/mapper/centos-swap: UUID="fc6c66c0-0790-4b9d-89b1-068410710219" TYPE="swap" 
/dev/mapper/centos-home: UUID="f07d25d8-9813-4c4e-a520-c6988bba1e75" TYPE="xfs" 
/dev/nvme0n1: PTTYPE="dos"

3.　parted -l

parted -l 命令会输出分区类型 ( msdos　gpt ) 参数 l (list)表示列出所有设备的分区信息。

4.　df -T

只可以查看已经挂载的分区和文件系统类型
