I installed quota using apt-get and followed some of the tutorials online.
I ran sudo edquota username
which opened nano and gave a chart for me to edit. What does the chart mean when it says soft, hard, etc.?
Is there a proper tutorial for quota on Ubuntu? What's the official website for quota?
Or is there another option for setting user disk limits?
Here is a quick and easy tutorial for setting up disk quotas. It also defines the differences of hard quota and soft quota. It also shows how to set a grace period.
It is generic and should work under any version of Ubuntu.
Hope this helps!
