The classic DOS prompt is c:\Windows>
which is set by using the system variable PROMPT to "$P$G". (With newer versions of Windows, it's not an environment variable but you can still use the prompt
command to set it.)
Change the value for PROMPT to add $_
where you see fit. That will add a new linefeed to the prompt. I added $s
to get a space after the >.
C:\Users\me> prompt $P$_$G$s C:\Users\me > dir \ Volume in drive C has no label. Volume Serial Number is 5CE6-9877 Directory of C:\ 08/22/2013 08:22 AM <DIR> PerfLogs 03/05/2014 10:25 AM <DIR> Program Files 03/05/2014 10:26 AM <DIR> Program Files (x86) 01/22/2014 05:14 PM <DIR> Users 01/22/2014 06:15 PM <DIR> Windows 0 File(s) 0 bytes 5 Dir(s) 36,451,704,832 bytes free C:\Users\me >
