Even though PowerShell is actually becoming the de-facto standard for scripting, there are still a whole lot of batch-scripts which are used for every day tasks and need to be maintained. And event there are always new things to discover.

To pass parameters to a batch-file isn’t really something new. With %1, %2 and so on you can access those parameters within the script. Noteworthy might be the fact, that %1 is the first parameter, while %0 is the name of the script itself.

What I didn’t know so far where some extra variables like %~f0, %~d0, %~p0 … as well as combinations like %~dp0; but then again, I’m not really so much into batch-scripting.

Here is a little overview about what I recently discovered, maybe it helps for someone else:

	Description	Example
%~f	complete path inlc. filename	C:\winnt\system32\x.cmd
%~d	drive letter	C
%~p	path	\winnt\system32
%~dp	complete path	C:\winnt\system32
%~sp	short path	C:\Progra~1\Intern~1 (for C:\Programme\Internet Explorer)
%~x	file extension	.cmd
%~nx	filename incl. extension	x.cmd
%~sx	short file extension	.doc (for .document)
%~a	file attributes
%~t	date and time of a file
%~z	size of a file
