Faking standard input on the Windows command line
提问by Ryan
I want to use Evernote's ENScript.exeto create new notes, entering the text and title as arguments. The problem is that ENScript only allows the text to be entered via a file or via standard input.
我想使用Evernote 的 ENScript.exe创建新笔记，输入文本和标题作为参数。问题是 ENScript 只允许通过文件或标准输入输入文本。
For my current workaround I use a .bat file to write the argument to a file, then call ENScript with the /sargument pointing to the file to read it in, but that forces the default title to the temporary file's filename (a behavior I do not want).
对于我当前的解决方法，我使用 .bat 文件将参数写入文件，然后使用/s指向文件的参数调用 ENScript以读取它，但这会强制将默认标题设为临时文件的文件名（我不这样做的行为）想）。
So my question is: Is there a way to "fake" standard input on the Windows command line so that I can use an argument (passed from another program) to generate the note text? The beginnings of the script would be something like
所以我的问题是：有没有办法在 Windows 命令行上“伪造”标准输入，以便我可以使用参数（从另一个程序传递）来生成注释文本？脚本的开头将类似于
ENScript.exe createNote /i %1
with the standard input following.
标准输入如下。

You are looking for a pipe operation that captures the output of one command and sends it as input to the next. This is a standard capability in most operating systems.
您正在寻找一种管道操作，它捕获一个命令的输出并将其作为输入发送到下一个命令。这是大多数操作系统中的标准功能。
The pipe symbol for Windows CMD is |
Windows CMD 的管道符号是 |
Your script could be as simple as:
您的脚本可能很简单：
@echo %~2|@ENScript.exe createNote /i %1
If your script is called MakeNote.bat, you would call it like
如果您的脚本名为 MakeNote.bat，您可以这样称呼它
MakeNote "your title" "This is the text of your note"

One can "fake" standard input by using redirection:
可以通过使用重定向来“伪造”标准输入：
command args... < filename args...
where the <means input redirection ("read standard input from the filename after the <instead of the terminal").
其中<意味着输入重定向（“从而<不是终端之后的文件名读取标准输入”）。
(Note that old Windows or DOS programs may read straight from the terminal, making input redirection useless; this hopefully won't apply to something as recent as Evernote.)
（请注意，旧的 Windows 或 DOS 程序可能会直接从终端读取，从而使输入重定向无用；这希望不适用于像 Evernote 这样的最新版本。）
For your example:
对于您的示例：
ENScript.exe < "%1"
Feel free to add more arguments before or after the redirection. For example, if your script will be called as script filename title, you will want to invoke ENScript /i "%2" < "%1".
在重定向之前或之后随意添加更多参数。例如，如果您的脚本将被称为 as script filename title，您将需要调用ENScript /i "%2" < "%1".
