How To View Other Users' Quotas

It has always been the desire of users on ECN UNIX computers to see other users' disk-space quotas. This document will describe the step by step process of looking up the current disk quota of another user.

Instructions

In order for the quota lookup to work, you must be logged on to the same UNIX server that stores the user's files.

First, find the home directory for the user. Use the finger command:

atom$ finger richmnixon
Login name: rich1981                      In real life: Richard M. Nixon
Office: BRNG 1206                         Home phone: 
Directory: /home/atom/d/richmnixon        Shell: /bin/csh
Affiliations: che                         Uid: 42
Expires: October 1, 2005                  Login group: other (1)
Department: Chemical Engineering          Classification: Former President
Account type: president                   Authorized by: stacey
atom$ 

Now lookup the user's home directory using the df command:

atom$ df /home/atom/d/richmnixon
/export/home/d     (/dev/dsk/c0t3d0s2 ): 2683542 blocks   987352 files
atom$ 

This will give the actual filesystem path that holds the user's directory. In this case, the actual filesystem path of /home/atom/d/richmnixon is /export/home/d.

Finally, request the quotas for the filesystem and look for the user's name in the list:

atom$ /usr/sbin/repquota -v /export/home/d | grep '^richmnixon '
richmnixon   -- 115221 199000 205000                6039      0      0
atom$ 

The meaning of each field is the following:

A zero (0) in the field for the limit means an unlimited quota.

Should the command /usr/sbin/quota return no results, it might mean that the user has no quota set.
