Hey Guys,



I am trying to get the serial number of our thunderbolt docks with ioreg or system_profiler to have an extension attribute for the docks in Casper.



So far I got this 



$ system_profiler SPThunderboltDataType



Thunderbolt:



    Thunderbolt Bus:



      Vendor Name: Apple Inc.

      Device Name: MacBook Pro

      UID: 0x0001000F01673350

      Firmware Version: 17,2

      Domain UUID: 3F75FB1E-3A50-C95C-B5FC-0FF493EC3B19

          Status: Device connected

          Link Status: 0x2

          Current Link Width: 0x2

          Receptacle: 1

          Cable Firmware Version: 1.0.16

          Cable Serial Number: C4M435600SSF797A5

          Link Controller Firmware Version: 0.11.0

      Port:

          Status: No device connected

          Link Status: 0x7

          Current Link Width: 0x1

          Receptacle: 2

          Link Controller Firmware Version: 0.11.0



        Thunderbolt 2 Express Dock HD:



          Vendor Name: Belkin International, Inc.

          Device Name: Thunderbolt 2 Express Dock HD

          Vendor ID: 0x13

          Device ID: 0x85

          Device Revision: 0x1

          UID: 0x001314414033FB00

          Route String: 1

          Firmware Version: 25,1

          Port (Upstream):

              Status: Device connected

              Link Status: 0x2

              Current Link Width: 0x2

              Cable Firmware Version: 1.0.16

              Cable Serial Number: C4M435600SSF797A5

              Link Controller Firmware Version: 0.14.0

          Port:

              Status: No device connected

              Link Status: 0x7

              Current Link Width: 0x1

              Link Controller Firmware Version: 0.14.0


I know that the Serial number is the UID underneath "Thunderbolt 2 Express Dock HD:"
UID: 0x001314414033FB00



I'm not really good with grep or awk to get just the serial number which starts with 1314... wouldn't mind the 00 in front of it. But right now I also get the other UID of the mac if I use grep...



$system_profiler SPThunderboltDataType | grep " UID: "



      UID: 0x0001000F01673350

          UID: 0x001314414033FB00


Any idea how to get that done?



Bear with me, I'm new to this :-D

Can you run this command and post the output? 



system_profiler SPThunderboltDataType -xml | awk '/<array>/,/</array>/{print}'


You may have better luck getting the right information by piping it into an xml format first, but I can't tell since I don't have a Thunderbolt dock. Unless you want to send me one to test with? :-D

Thanks!

I really would like to send you one, but I think my boss doesn't want to :-D

#!/bin/bash



## This makes a bunch of assumptions



checkme=0

tbdock="Thunderbolt 2 Express Dock HD:"



system_profiler SPThunderboltDataType | while read line

do

        if [[ "$line"  =~ "$tbdock" ]]

        then

                checkme=1

        fi



        if [ $checkme -eq 1 ] && [[ "$line" =~ "UID:" ]]

        then

                echo "$tbdock ${line##* }"

                checkme=0

        fi

done



exit 0

This Script gives the output:
Thunderbolt 2 Express Dock HD: 0x001314414033FB00



Thank you for that!



Is it also possible to cut the "0x"?

echo "$tbdock ${line##* }" | sed 's/0x//g'

Perfect!



Just what I needed. It works like a charm!
