Ach! I have sudo privileges on only a small subset of commands, dhog apparently being some home-rolled version of du. du is not a program I can `sudo.` So

%du  --max-depth 1 -h /fst/home/
du: `/fst/home/lost+found': Permission denied
<bunch more permissions denied messages>
...
5.9G    /fst/home/user1
<bunch more permissions denied messages>
...
3.4G    /fst/home/user2
etc.

I imagine anything that actually tries to look inside of users' filesystems won't work (and, rightly so). The admins have carefully created dhog so I can't find out much, I think, and of course dhog doesn't have a -h flag.
