许多文本处理命令（过滤器）可以从标准输入流或从文件中获取输入。
Many text processing commands (filters) can take input either from the standard input stream or from a file.
这种过滤通常是通过构造命令管道线来完成的，其中来自一个命令的输出被导入或重定向为下一个命令的输入。
Such filtering is most often done by constructing a pipeline of commands where the output from one command is piped or redirected to be used as input to the next.
由于tr是纯粹的过滤器，因此您将使用cat命令为其生成输入。
Since tr is purely a filter, you generate input for it using the cat command.
如同我们目前已经了解的许多文本命令一样，seb可以充当一个过滤器，或者从文件中获取其输入。
As with many of the text commands we have looked at so far, sed can work as a filter or take its input from a file.
现在，我们具备了一些基本的工具来实现管道和重定向，让我们研究一些常见的UNIX和Linux文本处理命令和过滤器。
Now that we have a couple of basic tools for pipelining and redirection, let's look at some of the common UNIX and Linux text processing commands and filters.
要将命令command1的输出作为过滤器command2的输入，您需要使用管道操作符(|)连接两个命令。
In order to use the output of a command, command1, as input to a filter, command2, you connect the commands using the pipe operator (|).
