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.
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。
The input filtering extension has been a part of PHP since V5.0 to make security easier for you to include.

Input data sets go through some operation (filtering, aggregation, or a join) in the early stages of the WebSphere DataStage job that reduces their size.
在WebSphereDataStage作业的早期阶段中，输入数据要经过一些操作的处理(过滤、聚合或连接)，这些操作会缩小数据的规模。
The use-when filtering occurs early in the setup of a transformation, specifically before any input document is loaded or any launch options are acted upon.
use-when筛选在转换建立的早期阶段进行，具体来说在加载输入文档或者启动选项生效之前进行。
The input filtering extensions provide a set of functions to parse and check input before you use it in your functions.
输入过滤扩展功能提供了一组函数来解析和检查输入，然后在函数中使用此输入。
If all else fails to prevent rf interference from being introduced into the input, external filtering of the device input paths may be required, as shown in Figure 3-7.
如果所有的措施都不能避免RF干扰进入测试输入端，那么就可能需要在设备的输入通路上进行外部滤波，如图3 - 7所示。
Therefore, such tools as spatial filtering etc. are essential to perform preprocessing of the input data.
因此，有必要采用空间滤波等手段，对输入数据进行预处理。
