您可以使用带有测试命令的正则表达式来搜索是否找到“NO_SUCCESS”字符串

$ SUC="SUCCESS SUCCESS SUCCESS SUCCESS SUCCESS"
$ NSUC="SUCCESS SUCCESS SUCCESS SUCCESS NO_SUCCESS"
$ [[ $SUC =~ .*NO_SUCCESS.* ]] && echo "something wrong" || echo "everything is ok"
everything is ok
$ [[ $NSUC =~ .*NO_SUCCESS.* ]] && echo "something wrong" || echo "everything is ok"
something wrong
