List block devices, including those which are not mounted.
sudo lsblk
Sample output:
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 465.8G 0 disk
|-sda1 8:1 0 1.5G 0 part
|-sda2 8:2 0 93.2G 0 part /media/win7
|-sda3 8:3 0 13.7G 0 part
|-sda4 8:4 0 1K 0 part
|-sda5 8:5 0 338.1G 0 part /
|-sda6 8:6 0 3.7G 0 part [SWAP]
`-sda7 8:7 0 15.6G 0 part
sdb 8:16 0 931.5G 0 disk
`-sdb1 8:17 0 931.5G 0 part /media/ciro/DC74FA7274FA4EB0
-f: show mostly information on filesystems:
sudo lsblk -f
Sample output:
NAME FSTYPE LABEL MOUNTPOINT
sda
|-sda1 ntfs SYSTEM_DRV
|-sda2 ntfs Windows7_OS /media/win7
|-sda3 ntfs Lenovo_Recovery
|-sda4
|-sda5 ext4 /
|-sda6 swap [SWAP]
`-sda7 ext4
sdb
`-sdb1 ntfs /media/ciro/DC74FA7274FA4EB0
-o: select which columns you want exactly. Most useful information for humans:
sudo lsblk -o NAME,FSTYPE,MOUNTPOINT,LABEL,UUID,SIZE
-n: don't output header with column names. Good way to get information computationally. E.g., get UUID of /dev/sda1:
sudo lsblk -no UUID /dev/sda1
