process supervisor in bash

supervise.sh

#!/bin/bash
#
# Spawn a process and restart it if it exits.
#
declare -i exit_code
declare -i pid

_cleanup() {
	echo "[$(date)]: sending TERM to pid $pid"
	kill -TERM $pid
	exit 0
}

trap _cleanup EXIT

while true; do
	echo "[$(date)]: spawning $1..."

	"$@" &
	pid=$!
	wait $pid

	exit_code=$?

	echo "[$(date)]: $1 exited with code $exit_code"
	sleep 1
done

Can you provide a manual on how to use this? I tried by creating a bash file bash.sh and then attach my program to it like bash.sh my_program.go It didn't work when I stopped the program

@kool927 what was the full output? How did you stop/kill the program?

It was printing in loop this
the program exited with code 0

Replacing "$@" to /bin/bash -c "$1" works as expected
