Script help

Hi ,
I have written script to connect to diiferent databases (sybase)and down load the data into flat files connectdb.sh .I want to run it parallel and if all are succesfully downloaded then call another script,but its not working

Code:
parllelproc.sh

nohup connectdb.sh db1 db1.txt &
nohup connectdb.sh db2 db2.txt &
nohup connectdb.sh db3 db3.sh &
chk_status=`ps -efl |grep connectdb.sh|grep -iv grep`

if [ $chk_status -gt 1 ];then
echo "Still downloading the files"
retry=true
fi
if [ $retry=true ]
then 
sleep 600 #[sleep for 10 mins and re try]
else 
if [ $chk_status -eq 0 ] ; then 
echo "successfully downloaded"
fi
fi
#call another script to merge all the files and load into another database

Regards,
MR

(1) Your script will check only once. Better put it in a while....do....done loop.

Code:
while [ `ps -efl |grep connectdb.sh|grep -iv grep` -gt 1 ]
do
    echo "Still downloading the files"
    sleep 600
done

OK

If you install GNU Parallel you should be able to do:
Code:
parallel -j0 connectdb.sh {} {}.txt ::: db1 db2 db3
