Open dos command prompt from java

[Tomer Ben-David]

Hi

Is there any way to open the dos command prompt from java (this black
dos window...)
I want to execute some dos command and to execute them using java code
that will run them inside that black dos window...

I know I can use...
Runtime.getRuntime().exec("run.bat", null);
and get a handle to its inputStream however this is not what I want
since I want to open that run.bat in the dos prompt ...

Execute "cmd.exe /k run.bat" to execute run.bat and keep the command window
open afterwards.

its ok I found the solution

Runtime.getRuntime().exec("cmd /c start run.bat");



However Now im facing another problem, anyone knows how can I redirect
the output of the dos prompt to a file AND as well that it stays in
the DOS prompt black screen?

Thanks

from the command line use redirection ">" as in

Dir *.java>javaFiles.txt

I suspect, but I do not know, that you'll be able to include this in command
lines passed to .getRuntime().exec() as well.

You may need to enclose the command line in quotes and use the /S switch as
well..

From a dos prompt, try cmd /? for more details on the switches for the cmd
executable.

I'd be interested in hearing the results of your experiments.

Hi

I found your articles very interesting and very clear! and i looked at
the exec utility that simplifies things, and read about the
inputstream issue with the process however, I dindnt find any clue
whether its possible to direct the output BOTH to a file AND to the
console! Im currently going to use, java service wrapper it kind of
performing it, it might interest you as well...

Hi, I played with it and didnt find any way to perform this. I'm
going to use java service wrapper (a simple search for "java service
wrapper") will direct you to it, since im going to be using a service
as well i found it usefull (and it did print the output of the dos
command both to the dos window and to a file...)
