bpcp [-r] [-p] <source> <target>

where
     -r  means recursive copying,
     -p  means the time stamp of <source> should be preserved,
     <source>, <target>  are either paths on the head node or of the form <node>:/<path on the node>.

bash-2.05b$ bpcp -p cpi 0:/scratch/gregory
bash-2.05b$ bpcp 0:/scratch/gregory 1:/scratch/gregory
bash-2.05b$ bpsh -d 0-1 ls -l /scratch/gregory
0       ---------------------------------------------------------------------
total 488
-rwxr-xr-x    1 gregory  11         495334 Jul 24 17:45 cpi

-rwxr-xr-x    1 gregory  11         495334 Jul 30 20:24 cpi

In the example above the first copy retained the original time stamp but not the second.
