ECHO %~dp0

Getting the parent directory of the Batch file being executed

The equivalent of dirname in bash

 
ECHO %~dp0
 

%0 contains the full path of the running .bat or .cmd file.

The ~ expansions can be applied to all numbered arguments (%0…%9) and to the one-letter variables used by FOR (e.g. %%a). The most commonly used expansions are:

• ~d: drive letter (with colon)
• ~p: directory path (without drive letter)
• ~n: file name without extension
• ~x: file extension (with leading dot)

So combining them into %~dp0 will work like dirname, while %~nx0 will work like basename.
