I have a script that executes some commands remotely, every time it runs it appends the time of execution to a log. I thought I was doing it right but then realized the script was sending the time/date of my machine, not using the server time/date in the log.
我有一个脚本，它远程执行一些命令，每次运行时都将执行时间附加到日志中。我以为我做得对，但后来意识到脚本发送的是我的机器的时间/日期，而不是使用日志中的服务器时间/日期。
This is the command I'm using right now:
这是我现在使用的命令:
ssh root@myserver "echo \"*** Log info of $(date -u) ***\" >> /var/log/app.log"
I tried using single quotes but it does not work at all the script shows an error.
我尝试使用单引号，但它根本不起作用，脚本显示错误。
Is there a better way to log that time to a file on the server?
是否有更好的方法将日志记录到服务器上的文件中?

Enclose the full command inside single quotes like this:
在单引号中包含完整的命令，如下所示:
ssh root@myserver 'echo "*** Log info of $(date -u) ***" >> /var/log/app.log'
