!/bin/bash

start the background script, then find the pid

myscript.sh & myscript_pid=$! echo "do some stuff" kill -9 $myscript_pid

!/bin/bash

maybe someone else started the background script myscript

myscript_pid=$(pidof myscript) echo "do some stuff" kill -9 $myscript_pid

!/bin/bash

wait until both scripts are done, allow control + c termination

function continuous() { date myscript.sh & anotherscript.sh & wait || return }

while true ; do continuous 2>&1 | tee -a $LOG sleep 10 || break done
