How to delete Chrome temp data (history, cookies, cache) using command line

Question

On Windows 7, I tried running this script but still cannot clear Chrome temp data. Can someone figure out what's wrong with the script? Where do Chrome store history and cache ? Thanks

ECHO --------------------------------------
ECHO **** Clearing Chrome cache
taskkill /F /IM "chrome.exe">nul 2>&1

set ChromeDataDir=C:\Users\%USERNAME%\AppData\Local\Google\Chrome\User Data\Default
set ChromeCache=%ChromeDataDir%\Cache>nul 2>&1  
del /q /s /f "%ChromeCache%\*.*">nul 2>&1    
del /q /f "%ChromeDataDir%\*Cookies*.*">nul 2>&1    
del /q /f "%ChromeDataDir%\*History*.*">nul 2>&1    


set ChromeDataDir=C:\Users\%USERNAME%\Local Settings\Application Data\Google\Chrome\User Data\Default
set ChromeCache=%ChromeDataDir%\Cache>nul 2>&1
del /q /s /f "%ChromeCache%\*.*">nul 2>&1   
del /q /f "%ChromeDataDir%\*Cookies*.*">nul 2>&1    
del /q /f "%ChromeDataDir%\*History*.*">nul 2>&1    
ECHO **** Clearing Chrome cache DONE

Answer 1

Actually my script works. The reason Omnibox history is not cleared because I chose to sync data to Google Account. So after running the script, if you reopen Chrome, it will restore Omnibox history. Thanks to @Sathya for the comment

Please check if it is having any permission issues. Try running the batch file with additional privileges (run as admin).

OR

Try opening the command prompt and type the commands one by one and check the response to identify where exactly it fails.
