I was wondering how to make available powershell variable in order to be read from the command line. Is that possible?
The command is
get-wmiobject win32_networkadapter -filter "netconnectionstatus = 2" | Select -Expand macaddress -Last 1 | set-variable -name mac1
There isn't Powershell in DOS, so I'd guess you have a CMD script (ie a .bat or .cmd file) that needs to assign a variable returned from Powershell. This is suprisingly quite tricky .
C:\>for /f "delims=" %i in ('powershell -command " & { get-wmiobject win32_networkadapter -filter 'netconnectionstatus
= 2' | Select -Expand macaddress -Last 1 } "') do set foobar=%i
C:\>set foobar=00:19:99:E1:98:32
C:\>echo %foobar%
00:19:99:E1:98:32
