I'm not, but that's gotten me before! ;-) However, if I had been in that
directory, the output of lsof would have looked like this:
$ sudo lsof +D /u04 2>/dev/null
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
lsof 62398 root cwd VDIR 10,4 512 4321 /u04
ksh 83726 user01 cwd VDIR 10,4 512 4321 /u04
lsof 104328 root cwd VDIR 10,4 512 4321 /u04
