예상대로 작동하는지 알려주세요.

(편집 중...OP의 답변을 기다리는 중)

가장 간단한 해결책은 루프를 함수 밖으로 이동하고 백그라운드에서 함수를 실행하는 것입니다.

#!/bin/sh


triggerPerformanceTest(){ 
  thisIp=$1
  ## the rest of your tests. Just use $thisIp the way you were using
  ## the $iplist variable.
}

IP_Addresses="192.168.2.33,192.168.2.34,192.168.2.35"
for ip in $IP_Addresses; do
    triggerPerformanceTest "$ip" &
}

그러면 각 IP에서 테스트가 시작되고 백그라운드로 보내기 명령을 사용하므로 테스트가 시작 &됩니다.거의동시에. 밀리초 정밀도가 필요하지 않다면 이것으로 충분합니다.

이미 답변을 수락했지만. 제 생각에는 parallel다음 명령을 사용하여 이를 달성 할 수도 있습니다.
