! you do want to miss this -- ultra ugly tricks in batch

here I will introduce three ugly tricks to do one simple task -- get the batch file path from inside

1. very ugly, appears very sophisticated, very profound

for /f %%i in ("%0") do set curpath=%%~dpi
cd /d %curpath%

[%0 returns the file path and name that your typed at command prompt to run the batch, and ~dp means to get drive and path]

2. much more simpler, and easier to understand

cd /d %~dp0

[see explanation in item 1]

3. simple and maybe can not be simpler

cd /d %0\..

[do I need to explain? ]
