Question

我编写了一个检查ntp服务的脚本。它会更新它，然后启动服务。

我在下面的脚本中做了三件事：

检查服务是否配置正确并且是否正在运行。然后，只是退出脚本。即什么都不做。
如果服务配置正确，则只需启动服务并退出脚本。
如果未配置服务，请停止服务 - ＆gt;配置服务 - ＆GT;开始服务。

从上面的场景中，scenario-1和scenario-3工作正常。但是在测试方案-2时，它会抛出以下错误：

〜＃sh ntpConfigure.sh ntpConfigure.sh：第3行：NTP_CONF.BAK = / etc / ntp.conf.backup：未找到 ntpd没有运行 /etc/init.d/ntpd未运行服务器time.myCompany.com /etc/ntp.conf已配置已经配置服务，启动ntp服务从ntpd开始 ntpConfigure.sh：第77行：echo服务已成功启动：未找到

知道为什么会抛出这个错误？我检查了一切，但我的代码看起来不错。功能与上述错误一起正常工作。有什么想法吗？

你误导了一个命令：第{77}行echo"应为echo "。
