Sorry, a noobie question....!

I want to use a linux cluster to copy a list of files. I want to split the processing over 3 nodes so that each node gets (more or less) an equal share.

My script (base.sh) to execute my copy script (copy.sh) looks something like:

Code:

#!/bin/bash

for NODE in 1 2 3
do
        /sw/egs/bin/dsh -w node0${NODE} -e "/home/ts/scripts/copy.sh"

done

My copy.sh file is:

Code:

#/bin/bash

IDIR="/home/ts/test2/temp"
ODIR="/home/ts/test3/
FARRAY=( "$IDIR"/*.R )
COUNT=${#FARRAY[@]}

THIS_NODE=
TOTAL_NODES=3


for i in `seq 1 $COUNT`
do

        THIS_FILE=${FARRAY[$i]}
        REM=`expr $i % $TOTAL_NODES`


        if [ $REM -eq 0 ]
        then
        $REM = $TOTAL_NODES
        fi
    

        if [ $REM -eq $THIS_NODE ]
        then 
                cp $THIS_FILE $ODIR
        fi

done

My questions:

1. How do I capture which node is running this job (THIS_NODE) in copy.sh?
2. How can I modify the base.sh script so that the total number of nodes can also be passed into the copy.sh script? (sys args? - how?)

Is there a better/shorter/sleeker way to do what I am doing? Any other suggestions?

thanks!
