Running script in Parallel
Hi Folks
I have a doubt. I have a script which is running with 2 input parameters

Code:
./GetDSLnkCount.sh <jobnumber> Parmfile.txt

I need to run the script in parallel for different jobnumbers. The commands are

Code:
./GetDSLnkCount.sh jnhuc14500 Parmfile.txt 
./GetDSLnkCount.sh jnhuc14501 Parmfile.txt 
./GetDSLnkCount.sh jnhuc14502 Parmfile.txt 
./GetDSLnkCount.sh jnhuc14503 Parmfile.txt 
./GetDSLnkCount.sh jnhuc14504 Parmfile.txt

So What I have done is I copied all the above commands to File and doing like this


Code:
cat File|
{
while read LINE
do
$LINE $
done
}

So do you think this will run all the command in parallel or this will be in a sequence mode ?

I guess you mean $LINE &, not $LINE $?

Change it to:
Code:
while read LINE
do
  $LINE &
done < File
wait

And see!

You will need the "wait", unless you run "$LINE" nohup, otherwise all of your commands running with "&" will die unceremoniously when your script finishes.

It would if it was waiting.

How long would you typically expect one of these "GetDSLnkCount.sh" jobs to run?
