A simple shell script function to keep a process running continuously, auto-restarting it if it stops or crashes.

keepalive.sh

keepalive() {
    local command_args=("$@")

    # Check if a command was provided
    if [ -z "$1" ]; then
        echo "Usage: keep_alive <command> [arguments]"
        return 1
    fi

    # Handle manual interruption (Ctrl+C)
    trap 'echo -e "\n[Interrupted by user] Terminating..."; return' INT

    echo "Starting monitoring for: ${command_args[*]}"

    while true; do
        # Execute the command
        "${command_args[@]}"

        # Logic for when the process exits
        echo "Process stopped at $(date). Restarting in 2 seconds..."
        sleep 2
    done
}
