I am new to UNIX and can't figure out how to use the 'quota' command to see my disk usages. So I install “quota” using the following command sudo apt-get install quota But when I type in the command quota -v or anything similar, it doesn’t show anything. According to most website online (http://acs.ucsd.edu/students/quota.shtml#check-remove) , it suppose to show me all the quota limitation when I type in quota -v. can you please tell me how can I make it work or if I am doing something wrong here. your help is greatly appreciated. Thanks.
