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.
这个参数设置在map/reduce任务中同时合并的输入流（文件）数量。
This parameter sets the number of input streams (files) to be merged at once in both map and reduce tasks.
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.
记号赋予器穿过输入流，每次检查一个字符，直到它遇到一个整数或者直至文件结束。
The tokenizer moves through the stream, inspecting characters one at a time until it encounters either an integer or the end of file.
当从多个文件或标准输入流创建输出时，可以使用当前日期和时间替换文件名和创建日期。
When output is created from multiple files or the standard input stream, the current date and time are used instead of the filename and creation date.
后者将打印由cat命令后所列文件组成的输入流中指定行数的内容，但将把输入流作为单个文件对待。
The latter will print the specified number of lines from the input stream made up of the files listed after the cat command, but treated as one single file.
该类实现了针对读取ZIP文件格式的文件的输入流过滤，包括支持压缩和解压项。
This class implements an input stream filter for reading files in the ZIP file format. Includes support for both compressed and uncompressed entries.
