early every linux system has a data manager. In my case, I have Nautilus because, I have a GNOME environment.

If I connect an external drive to my system, I can see the content in Nautilus with my users permissions.

My question is:

With which command as ROOT, I can see the content in a tree structure as 'ls -lh' in '\' ?

I did: findmnt -l to see if the device was mounted

TARGET /run/media/admin/cf7a4e4e-9f2f-4952-bca8-46ddce184885 [name of the device]

SOURCE /dev/sda1

FSTYPE ext4

OPTIONS rw, nosuid, nodev, relatime, secl

lsblk -l to see the size of the content

I really appreciate your help !!!


Solution:
It is easier as I thought:
As ROOT:
# cd /run/media/admin/cf7a4e4e-9f2f-4952-bca8-46ddce184885

Yes, it is. You might want to mark the thread as solved.

Is that a type? Did you try: ls -lh /

lsblk gives you the total size of a disk/partition device (/dev/sda1)
df gives you the total/usable and the actual/used size. df can work on the disk/partition device or on the mount point if mounted.
ls and other commands work on the mount point (/run/media/admin/cf7a4e4e-9f2f-4952-bca8-46ddce184885)
