Small update/correction to the above.  WRKACTJOB shows the following 
running under QBATCH:

CPYSAVFNFS   QSECOFR     BCH      .0  CMD-QSH          TIMW
QP0ZSPWP     QSECOFR     BCI     3.2  PGM-CP           TIMA
QZSHSH       QSECOFR     BCI      .0  PGM-QZSHSH       EVTW

CPYSAVFNFS is the name of the submitted job.  The submit job command looks 
like this:

SBMJOB CMD(QSH CMD('cp /QSYS.LIB/BACKUPS.LIB/* /mnt/backups')) 
JOB(CPYSAVFNFS)

This job started around 2:30 this morning and is still running.  Only 
4.1GB have been copied so far.

if you want to understand why that is, there are many good books on
the design of operating systems. please pass them along to redmond
when you're done reading them :)
