Get label of Linux storage partition device file

Question

Given the partition device file /dev/sdh1, I need to find out the label of this device.

dmesg doesn't mention its label while GParted reveals that it is called H2N_SD:

I need to build a way to be able to run something similar to

$ partlabel /dev/sdh1
H2N_SD

This question is nearly the opposite of getting device name & mount point from label.

Answer 1

Use blkid:

$ blkid -s LABEL -o value /dev/sdh1
H2N_SD
