I am writing my first udev rule. I read many how tos but can't find a way to assign ATTRS{variable} to ENV{variable}

in order to have access to that variable from RUN

like RUN+="/bin/mkdir/%E{variable}"

because with RUN+="/bin/mkdir/ATTRS{variable}" it doesn't work.

I tried to use $ATTRS{variable}, %ATTRS{variable}, ATTR{serial}, $ATTR{serial}, %ATTR{serial} with no success.

The variable itself exists 100%

thank you...

I would delete this question but, probably, this could save one's time

So I used: ENV{variable}="$attr{variable}"
