Linux : Using the sticky bit to control file permissions

More videos like this can be found on my website: http://www.theurbanpenguin.com

In this video we are going to take a look at file permissions in Linux. At first we need to understand that we can delete files that are read-only. Creations and deletions are controlled by directory permissions. We can, then in some instances write to files that are read-only as many applications delete the file and create a new one during edits. This must be controlled for security and we do this with the sticky-bit set in the directory permissions.
