Extensions to%0 in Windows cmd

Often see%~dp0 in batches, it seems difficult to understand.

In fact, it is%0, then use ~ to place between% and 0, add some definition fields to expand.

Echo%0
Echo%~0

This is made into a bat file that executes

E:\temp>echo "E:\temp\shenxu.bat"
"E:\temp\shenxu.bat"

E:\temp>echo E:\temp\shenxu.bat
E:\temp\shenxu.bat

%~0 is to remove the double quote "

%~F0 displaying the full catalog file

E:\temp\shenxu.bat

%~D0 Display Drive number

E:

%~P0 Display Path

\temp\

%~n0 display file name, not including extension

Shenxu

%~x0 Display Extension

Bat

%~S0 display shortened name, when the file name 8 bit, no change, more than 8 digits will display the top 6, and then add ~ and 1 and extension, and finally all of you into uppercase.

Shen12~1.bat

%~A0 Display properties, which are generally--a----
%~T0 Displays the time and date of the file
Echo 2015/08/11 15:49
%~z0 Display the file size

Then, they can be used in combination.

%~dp0 Show driver number good path

%~nx0 display file name and extension, in fact, full name

Sometimes see the%~DP1, actually is the expansion of%1, and so on the line.
