-How to Run the Top Command in Batch Mode
+如何在批处理模式下运行 Top 命令
 ======

-The **[Linux Top command][1]** is the best and most well known command that everyone uses to **[monitor Linux system performance][2]**.
+**[Top 命令][1]** 是每个人都在使用的用于 **[监控 Linux 系统性能][2]** 的最好的命令。

-You probably already know most of the options available, except for a few options, and if I’m not wrong, “batch more” is one of the options.
+除了很少的几个操作， 你可能已经知道 top 命令的绝大部分操作， 如果我没错的话， 批处理模式就是其中之一。

-Most script writer and developers know this because this option is mainly used when writing the script.
+大部分的脚本编写者和开发人员都知道这个， 因为这个操作主要就是用来编写脚本。

-If you’re not sure about this, don’t worry we’re here to explain this.
+如果你不了解这个， 不用担心，我们将在这里介绍它。

-### What is “Batch Mode” in the Top Command
+### 什么是 Top 命令的批处理模式

-The “Batch Mode” option allows you to send top command output to other programs or to a file.
+批处理模式允许你将 top 命令的输出发送至其他程序或者文件中。

-In this mode, top will not accept input and runs until the iterations limit you’ve set with the “-n” command-line option.
+在这个模式中， top 命令将不会接收输入并且持续运行直到迭代次数达到你用 “-n” 选项指定的次数为止。

-If you want to fix any performance issues on the Linux server, you need to **[understand the top command output][3]** correctly.
+如果你想解决 Linux 服务器上的任何性能问题， 你需要正确的 **[理解 top 命令的输出][3]** 。
