更有用的是，您可以将文件复制到标准输出，然后可以使用管道从标准输入中提取这些文件，并将它们从一个地方复制到另一个地方。

Even more usefully, you can copy files into the standard output and, then using pipes, you can extract the files from the standard input and copy the files from one location to another.

使用cat(其名称表示“连接”)来连接文件和标准输入流，如清单1所示。

Use cat, whose name stands for together, to concatenate files and standard input streams, as in Listing 1.

Why is this much nice? Well, that's a handy piece of code.
