Hi Georges,


Thanks a lot for your help.

I did the same:



public class CommandManager {

public static String getOutputCommand( String command ) throws Exception


      Process process = Runtime.getRuntime().exec( command );


      BufferedReader in = new BufferedReader(new InputStreaReader(process.getInputStream()));

      String result = in.readLine();


      return result;




It works perfect when I use a local command on windows and unix.

It still works when the command is a ssh on windows.

But does not work anymore for a ssh command on unix. I don't get anything!


>>> print CommandManager.getOutputCommand("/usr/bin/ssh lalanne@mrs-dv-00001  cat ~/temp/result375.txt'" )






But, on windows:


>>> print CommandManager.getOutputCommand("C:\\cygwin\\bin\\ssh.exe lalanne@mrs-dv-00001 'cat temp/result.txt'")

So, now I am totally blocked.


I don’t know how to get the output of my remote command …

The problem is that I need this output!


Any help will be really appreciated.

I use Java directly to execute the command and get the output from the

Java exec method

as shown below.  You will probably want to change the command string

provided to the

exec command.


Hope this helps.



# function to look for an executable file in the search path and to

return its

# full path.  Uses the UNIX 'which' command and assumes UNIX OS


def getExecPath(prog):

    retPath = ''                        # set to return empty string

    cmdAr =  ('which', prog)

    rt = java.lang.Runtime.getRuntime()

    proc = rt.exec(cmdAr)

    isr = java.io.InputStreamReader(proc.getInputStream())

    bufferedReader = java.io.BufferedReader(isr)


        progInfo = bufferedReader.readLine();

        if progInfo.startswith('/'):

            # looks like the right type of information

            retPath = progInfo





    return retPath
