[Discuss] Bash script help

[John Blomfield]

I want to test that my Android device is connected to my PC usb before 
doing other stuff on the ADT sdk in the script ...............

................
adb devices

#results in
List of devices attached
3230ce87e28a70b9        device
# if its connect or
List of devices attached

# and empty list if its not if I run

adb devices | grep 3230ce87e28a70b9

# I get
3230ce87e28a70b9        device
3230ce87e28a70b9
#How do I extract the number 3230ce87e28a70b9 as a variable $DEVICENUM 
so I can test it in an "if" statement e.g.

if [ 3230ce87e28a70b9 = $DEVICENUM ] ; then ......................more stuff

Thanks John
