How to get the path of a batch script without the trailing backslash in a single command?

Question

Suppose I wish to get the absolute path of a batch script from within the batch script itself, but without a trailing backslash. Normally, I do it this way:

SET          


        

Answer 1

I'd like to point out that it is not safe to use the substring tricks on variables that contain file system paths, there are just too many symbols like !,^,% that are valid folder/file names and there is no way to properly escape them all

FOR /D seems to strip the trailing backslash, so here is a version that uses for:

setlocal enableextensions enabledelayedexpansion&set _CD=%CD%&cd /D "%~dp0"&(FOR /D %%a IN ("!CD!") DO ((cd /D !_CD!)&endlocal&set "BuildDir=%%~a"))

This requires Win2000 and will probably fail if the batch file is on a UNC path
