To Display Hard Disk Partition Size in Mega bytes or GB or TB: $ df -HTo list all block devices, run:
# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 1 558G 0 disk ├─sda1 8:1 1 307M 0 part /boot ├─sda2 8:2 1 250G 0 part /webroot ├─sda3 8:3 1 6G 0 part [SWAP] ├─sda4 8:4 1 1K 0 part └─sda5 8:5 1 301.7G 0 part / sr0 11:0 1 1024M 0 rom
To determine the file system type or to find out what type of file systems currently mounted:$ df -T df command report filesystem disk space usage and if you pass -T option it will report filesystem type.
$ mount /dev/hdb1 on / type ext3 (rw,errors=remount-ro) /dev/hdb2 on /home type ext3 (rw,errors=remount-ro) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) tmpfs on /dev/shm type tmpfs (rw) usbfs on /proc/bus/usb type usbfs (rw) automount(pid3558) on /data type autofs (rw,fd=4,pgrp=3558,minproto=2,maxproto=4)
As you can see, second last column displays the file system type. For example first line [/dev/hdb1 on / type ext3 (rw,errors=remount-ro)] can be interpreted as follows:
- /dev/hdb1 : Partition
- / : File system
- ext3 : File system type
- (rw,errors=remount-ro) : Mount options
