在批处理文件中将输入传递到程序提示符 [英] Passing inputs to program prompt in a batch file

问题描述

我正在使用mpich2并行运行模拟.我的工作站具有相当严格的安全性，每次运行模拟时都必须使用新密码进行注册.我必须输入:

I am running simulations in parallel using mpich2. I've got rather stringent security on my workstation, and must register using a new password each time I run a simulation. I have to enter:

mpiexec -register

然后提示我输入用户名，然后提示我输入密码.不幸的是，似乎没有办法在单行上将用户/密码传递给mpiexec，例如

which then prompt me for a username, and then prompt me for a password. Unfortunately, there seem to be no way to pass the user/pass to mpiexec on a single line, e.g.

mpiexec -register user:pass

不起作用.

我正在尝试准备一个批处理文件，该文件可以自动将用户名和密码传递给mpiexec提示符，但似乎无法正常工作.我已经尝试过诸如timeout /t 5之类的各种方法，但这是行不通的.

I'm trying to prepare a batch file that can automatically pass the username and password to the mpiexec prompts, but I cannot seem to get it to work. I've tried various things like timeout /t 5 but that doesn't work.

谁能告诉我如何将这些输入传递给批处理文件中的mpiexec程序提示符?

Can anyone tell me how to pass these inputs to the mpiexec program prompts in a batch file?

谢谢！

我想我越来越近了.我已经尝试过

I think I am getting closer. I've tried

(
echo username 
echo password 
echo password 
) | mpiexec -register

似乎正在将用户名和密码输入传递给mpiexec提示符.但是，程序仍然挂在下一步-不确定我传递这些内容的方式是否有问题.

which appears to be passing the username and password inputs to the mpiexec prompts. Program is still hanging at the next step however - not sure if that's a problem with the way I'm passing these or not.

推荐答案

您可以重定向或管道到mpiexec.
重定向使用户/密码输入变得有点讨厌，因为在行尾经常有不需要的(和不可见的)空格.

You could redirect or pipe into mpiexec.
With redirection it's gets a bit nasty for user/password entries, as there are often unwanted (and unvisible) spaces at the line ends.

(
echo user
echo pwd
) | more > fetch.txt

在fetch.txt

用户<space>
pwd <space>

user<space>
pwd<space>

当您要抑制空格时，请改用文件重定向

When you want to suppress the spaces use a file redirection instead

(
echo user
echo pwd
) > file.tmp
< file.tmp mpiexec -register

在两种情况下(重定向或管道)，您都需要为程序提供所有输入，而不仅仅是用户名和密码.
您无法再通过键盘输入输入.

In both cases (redirection or pipe), you need to serve all inputs for the program, not only username and password.
You can't enter inputs from keyboard anymore.
