When the output of cat is not redirected to a file or another command's standard input, cat behaves as most command-line tools and send its output to the console.
当cat的输出没有被重定向到一个文件或另一个命令的标准输出时，cat表现出来的行为与多数命令行工具一样，即将其输出发送到控制台。
Also, since by default the LogParser reads from standard input, you can pipe a log file from a running server to the LogParser to get output generated in real time.
同时，虽然LogParser默认从标准输入中读取数据，但是你也可以指定一个来自运行时服务器的日志文件，用LogParser实时输出。
Because reports generated to standard output usually scroll past your screen, it's recommended that you use the -o option to write the output to a file (see Listing 2).
因为发送到标准输出的报告常常会在屏幕上一滚而过，所以建议使用- o选项将输出写到一个文件中(见清单2)。

您可以通过使用 -n选项改变这些命令发送至其标准输出的行数（当然，输出结果将随 XF86Config文件的内容而不同）
In the first example, we use cat to read the file and output it to standard output, which is piped into the standard input of FMT.
在第一个例子里面，我们使用cat命令来读取文件的内容，然后将内容输送到标准输出，标准输出通过管道机制作为命令fmt的标准输入。
