I have a USB key that contains my keepass2 password database and I'd like to perform some actions when it is plugged into my computer, namely:

  • Auto-mount it to some specific location
  • When the mounting is done properly, launching keepass2 on the password database file

Simple tasks I guess, but I can't find how to do that.

I'm using Ubuntu 12.10, and it auto-mounts the device as a "media usb-key" and tries to open the images on it (even though there are none).

What is the best way to do that and to disable the ubuntu auto-mounting (so it doesn't conflict) ?

You can do this with udev, you must write rules in separate file and put them to /etc/udev/rules.d

For example this rule describes udev to run /path/to/mount/script when usb is mounted and /path/to/umount/script when umounted.

SUBSYSTEMS=="usb", ACTION=="add", KERNEL=="sd[a-z]1", RUN+="/path/to/mount/script", OPTIONS="last_rule"
SUBSYSTEMS=="usb", ACTION=="remove", KERNEL=="sd[a-z]1", RUN+="/path/to/umount/script"

Here you can read complete manual.
