questions regarding methods of class 'Process'

[frag]

Hi!

What is the difference between Process.getOutputStream() and Process.getErrorStream()?

If I call a shellscript and this script has a 'usage' information which is display when calling it with the wrong parameters will I get this output with getOutputStream()?
What will getErrorStream() return? Things like 'permission denied', 'can't find file or folder', etc.?

Cheers

Hullo!

Lets see if I can take a stab at this one. The Process java class has three methods that sort of apply to your question - i think. Process.getOutputStream(), Process.getInputStream(), and process.getErrorStream(). These methods will allow you to control the flow of stdout, stdin, and stderr, respectfully. take a look at the man page for either of these processes to see the difference.

here is a link if you can't get to a man page:

hope this helps,
