repquota
Reading the systemPackage: quota
The quota report of a filesystem: who uses what, who is over their soft limit and since when. Read it before chasing a mysterious fault on an account that "cannot write any more".
What its options do in the lessons
From the same glossary the lessons render under their commands, so the two cannot disagree.
repquota -a- Reports quotas for every read-write filesystem that has them, instead of requiring one as an argument. This is the form that answers “who is close to their limit”.
