I guess script run single job at a time or you can use multiple scripts for multiple jobs at same time.

Something like (if there is "copy" in the script name then launch it in background):

for i in $PGM_LIST
do
    if [ "$i" != "-" ]
    then
        cd `dirname $PGM_DIR/$i`
        idx=`expr index $i 'copy'`
        if [ idx -ge 0 ]
        then
          Run_SQL `basename $i`  >> $LOG 2>&1 &
        else
          Run_SQL `basename $i`  >> $LOG 2>&1
        fi
     fi
done

Change it accordingly to your OS and shell.

Michel

Just add a new variable that you flip-flop and test, something like:

n=0
for i in $PGM_LIST
do
    if [ "$i" != "-" ]
    then
        cd `dirname $PGM_DIR/$i`
        idx=`expr index $i 'copy'`
        if [ $idx -ge 0 -a $n -eq 0 ]
        then
          Run_SQL `basename $i`  >> $LOG 2>&1 &
          n=1
        else
          Run_SQL `basename $i`  >> $LOG 2>&1
          n=0
        fi
     fi
done

Then the first copy will be in background and the next one in foregroung, then the following in background and the next in foreground...
You may have to add a "wait" command to be sure that the background process is completed before you start a new backgroung process.

Michel
