如何在Monit（monitrc）配置文件中包含特殊字符？

Question

操作系统：CentOS 7.4      Monit：5.14      WebServer：Nginx 1.12.2

如何在配置文件（/etc/monit.d/monitrc）上插入特殊字符（特别是＆＃39; @＆＃39;）？

我正在尝试执行以下操作：

#Monitor clamd @ amavisd service

  check process clamd@amavisd with pidfile /var/run/amavisd/amavisd.pid
  start program = "/usr/bin/systemctl start clamd@amavisd"
  stop  program = "/usr/bin/systemctl stop clamd@amavisd"
  if cpu usage > 99% for 5 cycles then alert
  if mem usage > 99% for 5 cycles then alert

但monit -t为＆＃39; @＆＃39;发出错误字符。我试过了：

1. ＆＃39; @＆＃39;和＆＃39; clamd @ amavisd＆＃39;
2. ＆＃34; @＆＃34;和＆＃34; clamd @ amavisd＆＃34;
3. \ @

对于其他服务，例如下面的amavisd，它就像一个魅力：

#Monitor Amavis-新服务

  check process amavisd with pidfile /var/run/amavisd/amavisd.pid
  start program = "/usr/bin/systemctl start amavisd"
  stop  program = "/usr/bin/systemctl stop amavisd"
  if cpu usage > 99% for 5 cycles then alert
  if mem usage > 99% for 5 cycles then alert
