sc0rpi0 Posted January 2, 2008 Posted January 2, 2008 I was curious concerning two common switchblade commands. What does the ">nul" do in this command: if not exist ....Documentslogfiles md ....Documentslogfiles >nul What does the"2>&1" do in the command: ipconfig /all >> ....Documentslogfiles%computername%.log 2>&1 Thanks very much.
