设置特定应用程序（如游戏）的时间限制
我想为Ubuntu上的某些特定应用程序（如游戏）设置时间限制。 有各种Windows应用程序可以执行此操作，包括HomeGuard程序阻止程序，它可以将某些应用程序的使用限制在一天中的特定时间，或限制应用程序在特定时间段内的使用。 Ubuntu有类似的软件吗？
我刚刚为此目的制作了以下脚本。 我把它命名为timelimit ：
#!/bin/bash #timelimit - Set daily time limits for specific applications #Licensed under the standard MIT license: #Copyright 2013 Radu Rădeanu (https://askubuntu.com/users/147044/). #Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: #The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software. #THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

别忘了让它可执行：
chmod +x timelimit
句法：
timelimit APP_NAME
重要：
- 您可以在终端中测试此脚本，但应该在系统启动时运行。 要使其在启动时运行，请参阅如何在启动时运行脚本？
-
如果您晚上不关闭计算机，则应在午夜重新启动此脚本。 为此，您可以添加一个cron作业，如：
00 00 * * * kill`pgrep -x timelimit` && timelimit APP_NAME

简单易用。 但用它来控制自己
timeout 15 totem将在15秒后退出程序。 但可以再次推出。 编辑并将timeout 添加到应用程序的.desktop’文件的exec字段
