Get a Dell Service Tag from the Command-Line

Hey, IT folks… how many times have you needed the service tag off a Dell computer but: a) the original image had been wiped, and the Dell Service Tag applet wasn’t re-installed; or b) you were remotely connected to a machine that didn’t have the applet for whatever reason; or c) there was a gigantic pile of papers, framed pictures, staplers, and other office paraphernalia that made moving the computer a big pain in the ass?

I used to use this trick on a regular basis a few years ago, but forgot about it until yesterday, when I needed the service tag off a Dell I was remotely connected to.

In Windows, open a command-prompt and type

wmic bios get serialnumber

In most flavors of Linux, you can type this at the command-line:

sudo dmidecode -s system-serial-number

Hope this helps!
