Quota handling

[Reinhard Doelz]

Hi all, 
We're running a 4D/80GT with 16 megs core and 2x380 megs disk memory 
as a multi-user machine on a network (DECNET - we're using 4DDN.)
Besides graphics, the iris is used as number-cruncher by several users, 
and this implies that I have to check the disk space frequently
in order to avoid reaching the 100%. This bothers me, and I know disquota
tools from CONVEX and CRAY. The workaround I use now is that I try to run 
groups of users in different partitions, which works fairly well. However,
now one user is able to sabotage his entire group. Therefore, I'd like to have

a disquota utility which
 
* measures the space used by a single user 
* compares this value with a value stored in a table 
* sets the user to a restricted shell enabling him to delete the files
  causing the trouble. 

I think that there might be some of you having the same problem. 
Thanks for any suggestions and hints.

Reinhard
