Any user can use the quota command to view their own quota report as shown in the previous example. However only the root user can look at the quotas for other users and groups. For example, say we have a filesystem, /dev/hdc1 mounted on /usr/users, with two users: jane and john. First, let's look at jane's disk usage and limits.

# quota -v jane

Disk quotas for user jane (uid 1003): 
Filesystem  blocks   quota   limit   grace   files   quota   limit   grace
 /dev/hdc1    4100       0       0               6       0       0

In this example, we see that jane's quotas are set to zero, which indicates no limit.
