如何仅显示作为服务运行的Shell脚本的输出？
我编写了一个shell脚本并将其安装在SystemCtl上以在启动上运行，一切正常，但是，如果我运行“ SystemCtl状态MyService”，它将显示我的所有脚本源代码，而仅我的脚本的输出，我的脚本看起来与此相似（如一个示例）：
while true
do
echo "pinging..."
ping -c 10 google.com
.... blah blah ....
.... blah blah ....
done
如果我执行SystemCtl状态myService，则显示我的代码“ ping ...”和ping输出，我该如何执行SystemCtl仅显示输出而不是代码？
这是我的SystemCTL状态和SystemCTL CAT输出：
$ SystemCtl状态检查器：

I write a shell script and installed it on systemctl to run on startup, everything works fine, however if i run "systemctl status myservice" it shows all my script source code instead only the outputs of my script my script looks similar to this (as a example):
while true
do
echo "pinging..."
ping -c 10 google.com
.... blah blah ....
.... blah blah ....
done
if i do systemctl status myservice it show my code instead "pinging..." and the ping output, how can i do that systemctl only shows the output instead the code?
Here is my systemctl status and systemctl cat outputs:
$systemctl status checkupserver:

您只是收到脚本的打印输出，因为您还没有告诉它如何从外壳中运行。
因此，您在这里有两个选择。
。告诉您的服务文件如何执行
两个选项中的任何一个都会为您提供以下输出：
You're just receiving the printout of the script because you haven't told it how it can be run from your shell.
So you have two options here.
or 2. Tell your service file how to execute the script
Either of the two options will give you the below output:
