Re: User process limitations..

[camthompson <camthompson () shaw ca>]

To enable user quotas on a partition in redhat ( dont know about other 
linuxes), add "usrquota" after "defaults" or whatever you have in its 
place in the fstab.... to edit a quota, type "edquota -u <username>"; 
might wanna read the man page on it first before you go editing away. 
Also you might wanna check out "ulimit".
