Quick DOS tip! GetMAC!
Aaron Silber showed me this little gem yesterday! Working with Citrix Provisioning Server lately, I have been up to my eyeballs in MAC addresses while finding and writing them down! 🙂 Normally, I would just type the good old IPCONFIG /ALL and sift through the output for the MAC addresses I was hunting for. Enter GETMAC for a much cleaner, faster, more direct answer from your computer. 🙂
Nice! Obviously a Microsoft only tip – You Linux readers are on your own! 🙂
