RE: [Jython-users] os.system and os.popen

Hi Georges,

=20

Thanks a lot for your help.

I did the same:

=20

=20

public class CommandManager {

public static String getOutputCommand( String command ) throws Exception

{

      Process process =3D Runtime.getRuntime().exec( command );

      process.waitFor();

      BufferedReader in =3D new BufferedReader(new
InputStreaReader(process.getInputStream()));

      String result =3D in.readLine();

      in.close();

      return result;

}

}

=20

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!

=20


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

=20

None

=20

=20

=20

But, on windows:

=20


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

I use Java directly to execute the command and get the output from the=20

Java exec method

as shown below.  You will probably want to change the command string=20

provided to the

exec command.

=20

Hope this helps.

#

# function to look for an executable file in the search path and to=20

return its

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

#

def getExecPath(prog):

    retPath =3D ''                        # set to return empty string

    cmdAr =3D  ('which', prog)

    rt =3D java.lang.Runtime.getRuntime()

    proc =3D rt.exec(cmdAr)

    isr =3D java.io.InputStreamReader(proc.getInputStream())

    bufferedReader =3D java.io.BufferedReader(isr)

    try:

        progInfo =3D bufferedReader.readLine();

        if progInfo.startswith('/'):

            # looks like the right type of information

            retPath =3D progInfo

    except:

        bufferedReader.close()

    else:

        bufferedReader.close()

    return retPath
