How do I list all storage devices (thumb drives/external hard drives) that are connected via USB, from the command line?
Solution 1:
If you are looking for the mounted disks, a simple
df
will list them along with all your other disks along with some useful info.
Solution 2:
I'd recommend checking the udev properties of the devices, specifically the ID_BUS property:
for device in /sys/block/*
do
if udevadm info --query=property --path=$device | grep -q ^ID_BUS=usb
then
echo $device
fi
done
