Batch file: for parameters

I am having trouble understanding what does following windows batch file do, can somebody explain:

for /f %%i in ("%0") do set curpath=%%~dpi
cd /d %curpath% 
/*Some other code...*/
cd /d %curpath%
Solution

  • %0 is the full path to the .bat file itself (if run from another directory) and ~dpi is a modifier to extract the drive and directory from a path omitting the file name, so this snippet sets the current drive & directory to the one in which the batch file lives.

    I can't see the reason for using a FOR, %~dp0 does the same thing in one go.
