Get only android device id and save it to an array in bash

Question

I am new to bash scripting and I want to write a script that gets only the device id from the bash output when I do:

adb devices

Result:-

List of devices attached 
06c3b9270b3fa34c    device

So in my array i only need 06c3b9270b3fa34c.

How can i write this in bash?

Writing code would be a good start. Some combo of `adb`, `tail`, and `awk` will probably do the trick. — Marc B, Jul 17 '14 at 17:37

Through grep,

adb devices | grep -o '\b[a-f0-9]\+\b'

the first one is good because it shows all the devices connected...the second one only shows one device id – MakeThingsHappen Jul 17 '14 at 17:42
removed the second one . – Avinash Raj Jul 17 '14 at 17:44
even clearer `adb devices | grep -o '\b[a-f0-9]\{10,\}\b'` assumed the id have atleast 10 digits. – Avinash Raj Jul 17 '14 at 17:46
but no i have like 5 devices...i want to store them in array how can i do that? – MakeThingsHappen Jul 17 '14 at 17:47
try `adb devices | grep -oP '\b[a-fA-Z0-9]{10,}\b'`. It would be better if you post all the possibilities. – Avinash Raj Jul 18 '14 at 00:46
now the pronlem is it also reads the:- of... devices... attached .... device...device....device... – MakeThingsHappen Jul 18 '14 at 17:10
