Get the last 4 characters of output from standard out

Question

I have a script that is running and uses

lspci -s 0a.00.1 

This returns

0a.00.1 usb controller some text device 4dc9
         


        

Answer 1

Do you really want the last four characters? It looks like you want the last "word" on the line:

awk '{ print $NF }'

This will work if the ID is 3 characters, or 5, as well.
