One advantage of pipes on Linux and UNIX systems is that, unlike some other popular operating systems, there is no intermediate file involved with a pipe.
Linux和UNIX系统中的管道的优点之一是，与其他流行的操作系统不同，它们的管道不涉及到中间文件。
The stage converts the data to a Teradata format and writes to a data file or a pipe.
工作台将数据转换为Teradata格式并将数据写入到数据文件或管道。
The FastExport utility reads the data from Teradata in Teradata format and writes the data to a pipe or a data file.
FastExport实用工具从teradata读取teradata格式的数据，并将数据写入到管道或数据文件。
To this end, we attach a "tee" (T-shape pipe) that permits two things at the same time: placing the output into a file AND displaying the output into the screen. The plumbing analogy would be.
为达到此目的，我们连接允许两件事同时进行的“tee ” (t -形管道)：将输出结果放在文件中同时将输出结果显示在屏幕上。

xml文件包含指定处理程序应属于哪个管道和阶段的规则。
The first two lines delete the existing tap file and replace it with another FIFO pipe.
前两行删除现有的tap文件，并用另一个FIFO管道代替它。
Format Type in this example is Delimited, as the fields in the data file are separated by a delimiter "|" (pipe).
本例中的FormatType是delimited格式，数据文件中的字段由分隔符“|”(管道)分开。
Therefore, it's useful for editing command output or for when you're preprocessing a file with other tools — you can then pipe that text output straight to sed for quick editing.
因此，它对于编辑命令输出或对于使用其他工具对文件进行预处理非常有用——然后您可以将该文本通过管道直接输出给sed，以进行快速编辑。
You can point it to a file, or pipe output through it to see the information one screen page at a time. For example, to show the contents of the Xfree86 startup log file one screen page at a time.
您可以将它指向一个文件，或者通过它以管道输出信息，以分页的方式来查看信息。
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。
The tee command functions as a T-pipe, taking its input (the output from the mainframe) and sending it to the next command as well as a file called tap.
tee命令的功能是作为t管道，将输入(主机的输出)发送到下一条命令和称为tap的文件。
You can also record the play by having the producer pipe the output into a recorded file.
通过让制作器将输出输送到一个录制的文件，您也可以记录剧本。
The pipe between the two (|) feeds the standard output from the first tar into the standard input of the second, effectively copying the files into, and then out of, a non-existent archive file.
两者之间的管道 (|) 将第一个tar 的标准输出传入到第二个 tar的标准输入，并且高效地将文件复制到一个并不存在的存档文件，然后再从其中提取文件。
The following code sample will capture TCP/IP data on both network interfaces and pipe to a file called network.log.
下面的代码将捕获两个网络接口的TCP/IP数据并保存到network.log文件中。
If message text returned by the db2 command is lengthy, consider using the "more" pipe (if available on your operating system), or redirecting the output to a file. For example.
如果db 2命令返回的消息文本过长，那么可以考虑使用“more”分屏显示(如果可以在操作系统中使用的话)，或将输出重定向到一个文件中。
This forces each file (the % s is a placeholder for the file name) to be pre-processed (hence the pipe, |) by tac.
这样可以强制使用tac对每个文件(%s是文件名的占位符)进行预处理(所以使用了管道|)。
All of the individual stop watch logs will be written to standard output (note that your servlet container may pipe standard output to a file on disk).
