在MATLAB中调用系统命令 [英] call system command within MATLAB

问题描述

我正在调用exe命令:

I'm calling an exe command :

myCmd = fullfile('working',myCommand.bat');
[status,message] = system(myCmd )

status = 0
message = 
processing value ...
complete
activating command ...
complete 

如何从消息中获取一些文字? 例如，我想获取第一个文本"和完成"以检查第一个操作是否完成?

How could I get some text from message ? For example i would like to get the "first text" and "complete" to check the first action is completed ?

谢谢

推荐答案

使用echo命令包含返回消息:

Use the echo command to include a return message:

[status,message] = system('yourCommand && echo hello world' )

将返回:

message =
      hello world

通常，您将需要创建一个字符串，在其中级联与&&连接的所有命令.然后，其中一个命令可以是echo something.

Generally you will need to create a string where you cascade all your commands connected with &&. One of the commands could then be echo something.

关于您的

output = 'processing value ...'    
command = ['cd ' myCMD ' && myCommand.bat' ' && echo ' output];
[status,message] = system( command )

将调用myCommand.bat并返回处理值...".

will call myCommand.bat and return "processing value...".
