Im trying to add the group Everyone and give it modify permissions on a folder. Im using a batch file to try this. so for I have icacls "C:\Program Files (x86)\Program File" /grant:r Everyone:M
But when I go and look at the permissions on the folder nothing has been changed.
No need to put :r after /grant. Check the examples by typing icacls /?
Do like this:
icacls "C:\Program Files (x86)\Program File" /grant Everyone:M
