extension attribute for Thunderbolt Dock: Serial Number

[L3nny5]

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
      Port:
          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

## 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

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

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

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

Thank you for that!

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

[sean · Accepted solution]

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

Perfect!

Just what I needed. It works like a charm!
