我正在尝试编写一个小型 bash 脚本来监视 RiotShield（英雄联盟的第 3 方玩家抓取工具）的输出是否崩溃。如果在日志中找到关键字，它应该终止该进程并重新启动它。

这是我的 bash 脚本：

#!/bin/bash
crash[1]="disconnected"
crash[2]="38290209"

                            echo "RiotShield killed!"
                            echo "Clearing log."
                            echo > log.log
                            echo "Starting RiotShield"
                            (mono RiotShield.exe …
