Try chmod

The best way to see what chmod does is to go to a Linux system and start using it. If you don’t have a Linux system close at hand, or don’t feel confident working with real files, the form below will let you test the chmod command.

Note: the form will only accept the "*" at the end of a filename as a wildcard. The Reset button will set the file permissions as they were when you first entered the page. The Help button will pop up a quick reference.
