Using dt
df -T /
result:
Filesystem Type 1K-blocks Used Available Use% Mounted on /dev/mapper/ubuntu--vg-root ext4 1920299296 1659133892 163549740 92% /
Using fsck
fsck -N /
result:

Using lsblk
The lsblk command is used for displaying the block devices in a Linux machine. You can add the -f flag for telling lsblk to show the file system type.
lsblk -f
result:

Using mount
mount | grep "^/dev"
result:
/dev/mapper/ubuntu--vg-root on / type ext4 (rw,relatime,errors=remount-ro,data=ordered) /dev/sda1 on /boot/efi type vfat (rw,relatime,fmask=0077,dmask=0077,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)
Using blkid
blkid /dev/sda1
result:
/dev/sda1: UUID="6FE9-28C1" TYPE="vfat" PARTUUID="8e53314c-0814-46cd-9f13-c2bb2b7a14b6"
Using file
sudo file -sL /dev/sda1
result:
/dev/sda1: DOS/MBR boot sector, code offset 0x58+2, OEM-ID "mkfs.fat", sectors/cluster 8, Media descriptor 0xf8, sectors/track 63, heads 255, hidden sectors 2048, sectors 1048576 (volumes > 32 MB), FAT (32 bit), sectors/FAT 1024, reserved 0x1, serial number 0x6fe928c1, unlabeled
Using fstab
cat /etc/fstab
result:
# /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> /dev/mapper/ubuntu--vg-root / ext4 errors=remount-ro 0 1 # /boot/efi was on /dev/sda1 during installation UUID=6FE9-28C1 /boot/efi vfat umask=0077 0 1 /dev/mapper/ubuntu--vg-swap_1 none swap sw 0 0
Using parted
sudo parted -l
result:
