How can I determine the address of a pen drive in Linux?

My task is to create a file on my pen drive dynamically - as soon as I insert the pen drive, the file should be created.

I would recommend using udev.

In Ubuntu at least (meaning that the drive automounts), a drive's files can be found under /media/<drivelabel>. The drive label is either something random if you didn't set one or what you set it to.

+1 for the UDEV Create an UDEV rule that runs a script, whenever a device with a specific UUID is inserted.

To determine the mountpoint of a device with e.g. uuid of "95738a33-589f-498d-8595-a81207f45dde", you can use the following ugly-but-working one-liner:

grep $(ls -lah /dev/disk/by-uuid/95738a33-589f-498d-8595-a81207f45dde | grep -o "sd[a-z]*[0-9]*") /etc/mtab |  awk '{print $2}'
