允许您启动和停止应用程序的 Linux shell 脚本

（编者注：以下是谷歌翻译的文本）

向你问好。我想创建一个允许启动或停止应用程序的 shell 脚本。 shell 脚本将采用启动或停止参数来分别启动或停止应用程序。显然，所涉及的应用程序必须在我们的 shell 脚本中指出。

预先感谢您..我对所有建议持开放态度

法语原文：

你好。请使用 shell 脚本来创建应用程序或下载应用程序。脚本 shell 会根据参数启动或停止相应的应用程序或停止应用程序。 bien évidemment l'application en question doit être indiquée dans notre script shell..

Merci d'avance .. je suis ouvert à toutes 提议

鉴于下面的 bash-script-template，您可以

  • 添加长选项--start并--stop设置变量并在 if 语句中使用它们。
  • 您可以检查start或stop是否在${remaining_args[@]}，然后使用该信息：
if printf '%s\n' ${remaining_args[@]} | grep -Pq '^start$' ; then
  start your app
elif printf '%s\n' ${remaining_args[@]} | grep -Pq '^stop$' ; then
  stop your app
fi

这是模板：
