How do I tell what my disk usage is?

Answer: 

To get a detailed listing of your quota usage type 'quota -v YOUR-USER-NAME' on a CoC UNIX system. This will show you:

$ quota -v YOUR-USER-NAME

Disk quotas for YOUR-USER-NAME (uid xxxxx):

Filesystem usage quota limit timeleft files quota limit timeleft

/tmp_mnt/net/hu5 19422 20000 21000 382 0 0

This will show your quota on the disks you have been allocated space. If you do not see one of the disks listed, it is because the automounter does not currently have the disk mounted. If you cd  into the directory in question, will mount it on your system. Now when you run quota you should see it listed.
