I propose you an enhanced version that launches samples and also closes automatically windows: ```sh #!/bin/bash ## associative array for job status declare -A JOBS results="" ## run command in the background background() { eval $1 & JOBS[$!]="$1" } ## check exit status of each job ## preserve exit status in ${JOBS} ## returns 1 if any job failed reap() { local cmd local status=0 for pid in ${!JOBS[@]}; do cmd=${JOBS[${pid}]} wait ${pid} ; JOBS[${pid}]=$? if [[ ${JOBS[${pid}]} -ne 0 ]]; then status=${JOBS[${pid}]} results+=" - $cmd : ${RED}FAILURE${NC}\n" else results+=" - $cmd : ${GREEN}SUCCESS${NC}\n" fi done return ${status} } #to colorize output RED='\033[0;31m' #RED GREEN='\033[0;32m' #GREEN NC='\033[0m' # No Color BOLD='\033[1;37m' tutos=$(ls tuto*) tutos="${tutos}\n$(ls ex*)" echo -e "parsing tutorials:\n$tutos" for t in $tutos;do background ./$t sleep 2 pkill sightrun done reap echo -e "\n------------------------------\n" echo -e "${BOLD}Results:${NC}\n\n$results" echo -e "\n------------------------------\n" ```
