What are UNIX permissions and how do I set them?
Permissions are what give a user control over his or her files. The user can control who has access to his files, by setting the permissions accordingly. Permissions of some kind are really necessary on a multi-user system. You wouldn’t want just anyone looking at your mail, or other sensitive files. This is controlled with permissions. On the other hand, if permissions on files that are supposed to be public (like web pages) are ‘cut off’ or have the ‘world readable’ permission set to ‘no’ then folks can’t see your web page. There are two ways to set permissions in UNIX, symbolically, and numerically. Either method works at cyberstation. You also need to know how to display access permissions.
