Stdin can also come from the standard output of another program , using the " | "( pipe ) operator of the shell , as follows

使用shell操作符“”（pipe）也可以使标准输入来自另一个程序的标准输出，如下所示

Most often , you provide stdin using the keyboard : You type the data you want sorted on a series of lines , for example .

多数情况下，您会使用键盘作为stdin：例如，您需要输入要排序的数据行。

In traditional programming languages such as C , you would use STDIN , STDOUT , and STDERR to accomplish this .

在诸如C之类的传统编程语言中，您将使用STDIN、STDOUT和STDERR完成此操作。

At each read from stdin , the current focus binary data ( as stored in @ win ) is reset to0 .

每次从stdin中读取时，当前的焦点二进制数据（存储于@win中）将被重设为0。

Sort reads the three lines you typed from stdin , sorts them , and writes the result to stdout .

sort从stdin读取您输入的三行文本，并对其进行排序，然后将结果写出到stdout。

PreviousRAR versions did not fill this field , resulting in meaninglessmodification time for stdin .

上一版RAR未填充该字段，导致标准输入修改时间错误。

These are sometimes called stdin , stdout , and stderr after the global variables that represent them in every C program .

有时将它们称为stdin、stdout和stderr，这是在所有C程序中用来表示它们的全局变量。

This program uses an iterator to read a line from stdin and another iterator to split the line into individual tokens .

此程序使用一个迭代器来从stdin中读取一行，同时另一个迭代器将该行分割成单个的标记。

You can force stdin to read from a text file , a device ( say , a probe connected to the computer ), or a network connection .

您可强制stdin从文本文件、设备（比如连接到计算机的探头）或网络连接中进行读取。

However , you can change the source of stdin and the eventual destinations of both stdout and stderr .

不过，您可更改stdin的源以及stdout和stderr的目标。

Like many other UNIX utilities , tar can write to and read from standard output ( stdout ) and standard input ( stdin ), respectively .

与许多其他的UNIX实用程序一样，tar可以分别向标准输出（stdout）写入、从标准输入（stdin）读取。

Both stdout and stdin are typically denoted as a hyphen ( - ) .

stdout和stdin通常表示为连字符（-）。

The commands to be run are read from a file specified with the-f option , or from stdin if-f is not used .

要运行的命令是从-f选项指定的文件读取的，如果没有使用-f，那么从stdin读取。

If you do have a filter that requires input from stdin , you might think of using the cat command to copy the file to stdout , which would work .

如果您有要求来自stdin的输出的过滤器，那么可以考虑使用cat命令将文件复制到stdout。

STDIN , STDOUT , STDERR , files , and in-memory data stacks are all handled in a uniform and elegant fashion .

文件和内存内部数据栈都以统一而优雅的方式处理。

After declaring variables ( most of which are used later in the focus timeout checks ), the program enters a loop listening for Synergy events on STDIN .

在声明变量（大多数将在稍后进行焦点超时检查时使用）后，程序将进入一个循环，对STDIN侦听Synergy事件。

Secondly , because sed is a stream editor , it can perform edits to data it receives from stdin , such as from a pipeline .

其次，因为sed是一种流编辑器，所以，它可以对从如管道这样的标准输入接收的数据进行编辑。
