In this article, I've run through the design of a library for processing command line arguments as an example of reflection in action.
在本文中，我讲述了一个用于处理命令行参数的库的设计过程，作为反射的一个实际的例子。
You can handle the actual processing of command line arguments with a single call, but the application first needs a way to define its particular parameters to the library.
您可以使用单个的调用来负责命令行参数的实际处理，但是这个应用程序首先需要以某种方式将它的特定的形参定义到库中。
The test case consists of some simple command argument processing followed by a loop that calculates the factorial of the specified values (if any).
测试用例包含几个简单的命令参数处理，然后是一个循环，它计算指定值(如果有的话)的阶乘。
Command-line processing is another pain point that developers typically don't approach in a structured manner.
命令行处理是另一个难点，开发人员通常不会采用结构化的方式来解决。
Command processing is asynchronous; multiple commands can execute simultaneously.
命令处理是异步的，多个命令可以同时执行。
Wouldn't it be nice if there were a command to let you prioritize how the kernel schedules its processing?
如果有一个命令能让您对内核的处理计划设置优先级，是不是就完美无缺了？
Once all the command line arguments are processed, the actual processing of the input starts, using the options and input and output sources and targets specified.
一旦处理了所有的命令行参数，就使用这些指定的选项以及输入、输出源和目标来开始输入的实际处理。
Can reflection simplify your command line processing?
反射是否能简化您的命令行处理？
Command-line processing typically requires both a short and a long name for the same command option.
命令行处理通常同时需要同一个命令选项的短名称和长名称。
You should also be able to write custom AWK programs to perform complex text processing from the UNIX command line.
您还应该能够编写自定义的AWK程序，以使用UNIX命令行执行复杂的文本处理。
This month I'm going even further by looking at an application that seems to be a good match for reflection's strengths and weaknesses: a library for command line argument processing.
在本月这一期的文章中，我将通过查看一个应用程序来更深入地讨论这一问题，这个应用程序是用于命令行参数处理的一个库，它能够很好地体现反射的强项和弱点。
More capacity is as simple as starting a new JVM with the same command line above, save for a new unique server id, easily providing additional processing resources.
要获取更多容量，只需使用上面的命令行(但需提供一个新的惟一服务器ID)启动一个新JVM，轻松提供其他处理资源。
You can use this version of the script to test and verify that the command line processing does what is expected of it.
可以使用脚本的这个版本测试和检查命令行处理是否符合期望。
When the column value changes, row processing breaks and performs the actions specified in the COMPUTE command, and then the specified SKIP action in the break command is performed.
当列值发生改变时，行处理中断并执行COMPUTE命令中指定的动作，然后执行BREAK命令中指定的SKIP动作。
Processing the command line parameters and options

The main features of the Engine are: UI module group locating, UI module caching, Command bundle processing, Selenium APIs re-implemented in jQuery, and new Tellurium APIs.
这个引擎的主要特性包括：UImodule组定位、UI module缓存、命令集处理、用jQuery重新实现的SeleniumAPI以及新的Tellurium API。
You can use this script from your crontab list for regular processing or run as required from the command line.
您从crontab列表使用此脚本进行常规的处理，也可以根据需要从命令行运行该脚本。
To configure the audit facility to monitor all event types, logging both successful and failed attempts, as well as using the audit error processing option, issue the following db2audit command.
为了将审计功能配置成监视所有事件类型，同时记录成功的和失败的尝试，并且使用audit错误处理选项，可发出以下db2audit命令。
The getopts command returns true if an option is found, so a common option processing paradigm uses a while loop with a case statement as in this example.
如果找到一个选项，则getopts命令返回true，因此常见的选项处理范例使用带case语句的while 循环，本例中就是如此。
Using powerful tools like sed and Perl, and the magic of regular expressions, you can easily do complex text processing tasks directly on the UNIX command line.
使用像sed和Perl这样功能强大的工具，以及神奇的正则表达式，您可以直接通过UNIX命令行轻松地完成复杂的文本处理任务。
For complete flexibility, in Unix-like systems with a popen function, you can pre-process the file with text processing utilities before it is passed into the plot command.
为了获得更完全的灵活性，在具有popen函数的unix类系统中，在将文件传送给plot命令之前，可以使用文本处理实用程序对文件进行预处理。
Using <<, also known as a here-document, can save some formatting time and is easier on the processing time of the command execution.
使用 <<（也称为here-document）可以节省格式化时间，并且使命令执行的处理更容易。
To begin the inactivity processing, run the command perl process_racluster.pl with the same privileges as the ID that ran Argus (usually root).
要开始进行对非活动状态的处理，用拥有运行Argus的权限的ID(通常为根用户)运行命令perl process_racluster . pl。
Running this command tells the JVM to take a "heap dump snapshot" and save it to a file for processing, usually using the jhat utility (which I introduced in a previous article).
运行该命令通知JVM拍摄一个“堆转储快照”，并将其保存在一个文件中以便处理，通常使用jhat实用工具(我在上一篇文章中介绍过)。
Many of the previous Speaking UNIX columns (see Resources) have presented the find command — an invaluable utility for scanning and processing files or even the entire UNIX file system.
在以前的对话unix专栏(请参见参考资料部分)中曾多次介绍了find命令，这是一种非常有用的实用工具，可用于扫描并处理各种文件，甚至整个UNIX文件系统。
GShell is a command line processing environment for executing most of the Community Edition commands. Table 2 displays the various GShell commands.
GShell是用于执行大多数CommunityEdition命令的命令行处理环境。
With NcFTP, you can run commands from the command line, which makes it ideal for scripting, and NcFTP can also resume a failed FTP transfer, as well as provide batch processing facilities.
可以使用NcFTP从命令行执行命令，这对于脚本编程非常理想，NcFTP还可以继续失败的FTP传输并提供批处理机制。
If you're processing large amounts of data, fscanf will probably prove valuable and more efficient than, say, using file followed by a split and sprintf command.
如果要处理大量数据，fscanf将能证明自己的价值并比使用file附带split和sprintf命令更有效率。
TFS Version Control command processing was re-written to support unlimited sized operations on key commands without being memory bound on the server.
Office Word和Excel文件在服务器上处理的速度快了TFS版本控制命令处理经过重写后，能够在不需要绑定内存到服务器上的情况下，支持无限量的关键命令操作。
Perhaps you are performing a job requiring a lot of command-line processing with arguments and would like to set a few aliases.
或许您正在执行一份需要大量的命令行来处理参数的工作或者您想要设置一些别名。
