find mount point given device

kornelix · 04-10-2007, 04:21 PM

I need to find removable USB drives and their mount points.

I can find USB devices at least two ways:
1. $ udevinfo -e (look for devices with ID_TYPE=disk, ID_BUS=USB)
2. $ /dev/disk/by-id (look for "USB Flash" in file name) (symlink to /dev/xxx)

I can then find the mount point by looking for the device in /etc/mtab.

This seems an awful mess for such a simple task. Is there a simpler way?

thanks

Have you tried the command 'lsusb' in a console? It may give you *some* of the information you want, though I am not sure if it will give you mount points. I haven't got any USB drives to try it on.
On the other hand, it doesnt look as though it gives the type of info you want.

USB (and SCSI) CDROMs are, for example, /dev/sr0. The file /proc/mounts list all mounted devices. So, you could find all mounted USB CDROMs via a command like MNT_CDS=$(awk '$1 ~ /\/dev\/sr[0-9]+$/ { print $2 }' < /proc/mounts).
