lsblk

• Run lsblk to get a list of all storage devices and their partitions
• To get all disks and partitions, with helpful information to identify drives besides their sdX IDs, use grep or sed to search for "disk" and "part"
  • lsblk -o NAME,UUID,PARTUUID,TYPE,PATH,SERIAL | grep 'disk\|part'
  • lsblk -o NAME,UUID,PARTUUID,TYPE,PATH,SERIAL | sed -n '1p;/disk\|part/p'

List of options for -o

After 30 seconds of searching for a complete list of variables you can pick from, I gave up and asked ChatGPT to create the list below, so keep that in mind if something doesn't work.
