Sticky

Further to the back up stuff I been documenting recently, I was told of this useful (?) little titbit. I have a spare disk called /dataStore that is mounted locally on my workstation. Other people log in to my computer to compile stuff, maybe run some stuff etc. So I am letting them back their stuff up locally on my computer. In order to give them the appropriate permissions on the data disk I have made a directory in this disk called imaginatively enough backup.

I have made this directory group writable so that everyone can use this disk. However, in order to ensure that no one fucks up anyone else's data I have made the directory a sticky. To do this type:

chmod +t dir

This is as close to an explanation as I could find:
