我有一个脚本,需要多次杀死由高可用中间件管理的资源。它基本上检查资源是否正在运行并在之后终止它,我需要获得进程真正被杀死的时间戳。因此,我编写了以下代码:
#!/bin/bash
echo "$(date +"%T,%N") :New measures Run" > /home/hassan/logs/measures.log
for i in {1..50}
do
echo "Iteration: $i"
PID=`ps -ef | grep "/home/hassan/Desktop/pcmAppBin pacemaker_app/MainController"|grep -v "grep" | awk {'print$2'}`
if [ -n "$PID" ]; then
echo "$(date +"%T,%N") :Killing $PID" >> /home/hassan/logs/measures.log
ps -ef | grep "/home/hassan/Desktop/pcmAppBin pacemaker_app/MainController"|grep -v "grep" | awk {'print "kill -9 " $2'} | sh
wait $PID
else
PID=`ps -ef | grep "/home/hassan/Desktop/pcmAppBin pacemaker_app/MainController"|grep -v "grep" | awk {'print$2'}`
until [ -n "$PID" ]; do
sleep 2
PID=`ps -ef | grep "/home/hassan/Desktop/pcmAppBin pacemaker_app/MainController"|grep -v "grep" | awk {'print$2'}`
done
fi
done
但是使用我的等待命令时,我会收到以下错误信息:wait: pid xxxx 不是此 shell 的子进程
