Yes it was a bad pase, here is the script (unles you meant something else):
#!/bin/sh
BTN=/dev/input/event0
while true; do
BTNVAL=`hexdump -e '8/2 "%x " "\n"' -n 16 $BTN | grep ' 74 ' | awk
'{print $7}'`
if [ "$BTNVAL" = "1" ]
then
echo "Power button pressed"
/sbin/sync
/sbin/sync
/sbin/shutdown -h now
/sbin/shutdown -h now
exit
fi
sleep 1
done

Also I forgot to mention, that in the script I actually have to put
the line /sbin/shutdown -h now twice... Otherwise after I press the
button the message that the system is going down is displayed, but
the system is not turning off. Then I press it again and its going down.

Hello there,
I am using Console version of debian provided on elinux.org
<http://elinux.org> on BeagleBone Black. My problem is that it
misses the power button functionality. I have found this script
for handling it:
|
#!/bin/sh
BTN=/dev/input/event0
whiletrue;do
BTNVAL=`hexdump -e '8/2 "%x " "\n"' -n 16 $BTN | grep ' 74 ' |
awk '{print $7$
if [ "$BTNVAL" = "1" ]
then
echo "Power button pressed"
/sbin/sync
/sbin/sync
/sbin/shutdown -h now
exit
fi
sleep 1
done
|
I have put a link to it into init.d and used update-rc to make it
work at startup.
The problem is that it doesnt always work. Im not sure either it
is running in the background or not, because when i use ps
command i dont see the script running and even though the power
button works. So lets say every 3rd power up the power button
doesnt work... Im not sure whats the case. I would also
aprichiate if someone told me either this is the proper way of
handling the power button in the official bigger image.

There is problems with the script, not sure if it was a bad paste or not.
