How to print the file system type of a mount

Linux supports several file systems, including VFAT, ext2, ext3, ext4 and Reiser. The ext* family of file systems are probably the most popular ones.

The quickest way to view the file system on which each FILE resides, or all file systems is the “df” command.

$ df -Th
Filesystem     Type      Size  Used Avail Use% Mounted on
udev           devtmpfs  481M  4.0K  481M   1% /dev
tmpfs          tmpfs      99M  1.2M   98M   2% /run
/dev/sda1      ext4       46G   32G   12G  73% /
none           tmpfs     4.0K     0  4.0K   0% /sys/fs/cgroup
none           tmpfs     5.0M     0  5.0M   0% /run/lock
none           tmpfs     494M   12K  494M   1% /run/shm
none           tmpfs     100M   36K  100M   1% /run/user

In the above example, with "df -Th", we can see the file system type
("-T" option) in a human readable ("-h") size format.
