Re: cron question about multiple commands
"echo ; ls" will execute both echo and ls, whatever is echo exit code.

"echo && ls" will execute ls only if echo exit code is 0.

Maybe you should do a script. Complex lines in crontab make it not clear and harder to maintain.

我有做個小實驗,簡單來講exit code;會傳回最後一個
但是&&會兩個看有沒有有沒有成功
