Here is the way I use CRON and STUFFKEY
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
( very messy , if you know a better way then let me know , Please )

sys:etc\crontab:-
=================
# file to call the StuffKey keyboard program and run clnolog.sky
# placed here by Josh to clear the Not-logged-ins
#Min Hr   Dat  Mo   Day   Command
00   *    *    *    1-5     load stuffkey sys:etc\clnotlog.sky /d=250
20   *    *    *    1-5     load stuffkey sys:etc\clnotlog.sky /d=250
40   *    *    *    1-5     load stuffkey sys:etc\clnotlog.sky /d=250
# Clean out the Student Home dirs.
30   4    *    *    1-5     load stuffkey sys:etc\clnstud.sky /d=250
---------------------------------------------------------------------

sys:etc\clnotlog.sky:-
======================
# Load Monitor and clear Not-Logged-Ins
#--------------------------------------------
# Start at the console screen and load monitor
<screen=System Console>
load monitor<cr>
# Wait for the monitor screen to be created and make it current
<waitfor screen=Netware 4.x Console monitor>
# Go to Conections screen
con<cr>
<waitfor text=Active Connections>
# set to Name order and goto last Not-Logged-in to see it happen
<f3>n<cr>
<dn><dn><dn>
# Press F6 to clear not-logged-ins
<f6>
# Exit Monitor
<esc><esc>Y<cr>
<waitfor screen=System Console>
cls<cr>
time<cr>
-------------------------------

sys:etc\clnstud.sky:-
======================
# Load ToolBox and Delete Contence of Home Student dirs
#------------------------------------------------------
<screen=System Console>
load toolbox.nlm<cr>
# Wait for the Toolbox to load
<waitfor screen=System Console>
sys:etc\\clnstud.ncf<cr>
<waitfor screen=System Console>
<cr><cr>
unload toolbox.nlm<cr>
<waitfor screen=System Console>
cls<cr>
time<cr>
-------------------------------

sys:etc\clnstud.ncf:-  ( part of )
=====================
del sys:student\home\17901\*.* /syq
del sys:student\home\17902\*.* /syq
del sys:student\home\17903\*.* /syq
del sys:student\home\17904\*.* /syq
del sys:student\home\17905\*.* /syq


To make this file is easy than you think:
=========================================
a) do a dir of sys:student\home\*. > homedir.txt
b) open home.txt in MS Excel as Text with space Delimited
c) now you have the different info in columns
d) delete the not required colums so you just have one column left
eg:-
17901
17902
etc...
e) insert a column infront of the Dir names
f) type: "del sys:student\home\" in the top cell and fill it down to the end
g) type \*.* /syq in A3 and fill down with that
h) Save it as "," delimited ( still .txt )
i) you should have:- "del sys:student\home\,17901,\*.* /syq
j) use any dos editor and find and replace:- replace "," with ""

Looks like a big job but is better than changing the last few digets in a 
450 line long text file.

---=== *!* Warning *!* ===---
the Toolbox DEL command in this format will delete any file or subdir
No Matter how you try and Flag it ( DIRI , RO it goes !!!!! )
Thats why I could not do a deltree syle from the root of Home\

Enjoy , Josh
