This tells the files open but not the program that opened them and, again no 
arguments.  Also, I have to be 'root' to list the directory.

Coastal:/proc/29589/fd # l
total 0
dr-x------    2 root     root            0 2004-04-16 20:58 ./
dr-xr-xr-x    3 filepro  users           0 2004-04-16 20:58 ../
lrwx------    1 root     root           64 2004-04-16 20:58 0 -> /dev/pts/2
lrwx------    1 root     root           64 2004-04-16 20:58 1 -> /dev/pts/2
lrwx------    1 root     root           64 2004-04-16 20:58 2 -> /dev/pts/2
lrwx------    1 root     root           64 2004-04-16 20:58 3 -> 
/appl/filepro/fpcust/key
lrwx------    1 root     root           64 2004-04-16 20:58 5 ->

lrwx------    1 root     root           64 2004-04-16 20:58 6 -> 
/appl/filepro/fpcust/index.B
Coastal:/proc/29589/fd #

I can get the program from /proc/$PID/exe

Coastal:/proc/29586/fd # cd /proc/29589
Coastal:/proc/29589 # l
-r--r--r--    1 root     root            0 2004-04-16 21:04 cmdline
-r--------    1 root     root            0 2004-04-16 21:04 environ
lrwxrwxrwx    1 root     root            0 2004-04-16 21:04 exe -> 
/appl/fp/dclerk*
dr-x------    2 root     root            0 2004-04-16 21:04 fd/
Coastal:/proc/29589 #

but again, no arguments.
