lsblk Command: How to List Linux Disks and Partitions

The lsblk command on Linux displays information about all block devices connected to the system. It is useful for viewing all connected disks whether they are mounted or not.

The most common options are:

• -a, --all       Also shows empty devices;
• -d, --nodeps    Shows information about the device only, without showing, for example, the partitions;
• -f, --fs             Shows detailed information about the filesystems;

Example of usage:

$ lsblk NAME        MAJ:MIN RM  SIZE RO TYPE MOUNTPOINTsda           8:0    0   64G  0 disk ├─sda1        8:1    0    1G  0 part /mnt└─sda2        8:2    0   63G  0 part   ├─cl-root 253:0    0   41G  0 lvm  /  ├─cl-swap 253:1    0    2G  0 lvm  [SWAP]  └─cl-home 253:2    0   20G  0 lvm  /homesr0          11:0    1 1024M  0 rom  

The -d option displays the information without the partitions:

$ lsblk -dNAME MAJ:MIN RM  SIZE RO TYPE MOUNTPOINTsda    8:0    0   64G  0 disk sr0   11:0    1 1024M  0 rom  

The -f option can be useful for viewing the UUID of devices:

$ lsblk -fNAME        FSTYPE LABEL UUID            MOUNTPOINTsda                                                                  ├─sda1      xfs          1c3b15b1-cd13(...)   /mnt└─sda2      LVM2_member  GZXwoc-7Ziass(...)  ├─cl-root xfs          602fcf7d-d716(...)   /  ├─cl-swap swap         a873901e-5b33(...)   [SWAP]  └─cl-home xfs          fcbdceb1-9053(...)   /homesr0
