Answer 1

When you are in the folder with the scripts run this bash script/command:

for var in $(ls *.pl)
do
    $var &
    # 5 simultaneous jobs 
    while test "$(jobs |wc -l)" -gt 4 
    do
        sleep 1
    done
done

this relies on you not having other background jobs running, test this by writing “jobs” on the commandline.
