chmod -R 777*
Hello, I use windows XP on a small server. Lately I downloaded a software (hydrological computation) which asked me to install as well ‘cygwin’ and then to perform in cygwin window the command: ‘chmod –R 777 *’ in order to give writings permission and allow the software to perform. I admit, I did not check, this instruction came from serious people….But I started to frick out when I realized that this command did not only change the permission of files related to the software or cygwin, but of all the files on my computer, it even started to process on the content of a dvd that was in my computer and I stopped the process since I was fearing that it would continue to the server’s disks….. I immediately perform a system restore at 1week before, but I am not sure I am OK with the permissions of sensitives windows files. Indeed, the dll files in the windows/system folder show a read/execute and write permission to everyone for example. It might have been like this before the problem with the ‘chmod’, but I can not tell and I worry I did something wrong. Is there any way to check the proper permission configuration on windows XP or to restore it? Any suggestion or help will be very very appreciated.

Windows doesn't care about permissions, it uses 777 for everything, and that is the default (everything has that permission, text, pictures, music, zip archives, ...). You don't need to change it, but if you do, you have to be careful to keep executables with the executable permission, or they won't run. -- René Berber -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

Also dynamic libraries need the executable bits to be used... just ran into that one. Windows sort of cares about permissions, probably that's why the default is 777. -- René Berber -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

The default permissions are rather 0700, plus an extra 7 for Administrators and SYSTEM. Have a look into your $USERPROFILE directory. Typically only you have full control permissions on your files, Administrators and SYSTEM. But nobody else has any permissions.
