Got something from here
udev does not run these programs on any active terminal, and it does not
execute them under the context of a shell. Be sure to ensure your program
is marked executable, if it is a shell script ensure it starts with an
appropriate shebang <http://en.wikipedia.org/wiki/Shebang_(Unix)> (e.g.
#!/bin/sh), and do not expect any standard output to appear on your
terminal.
