Arduino Yun - Process does not appear to work as expected

I have attempted to do something which should be very simple - code snippet (bzero and strcpy are my own procedures):

// Set up the pin 13 LED and use it to display the status of the Yun bridge
pinMode(13,OUTPUT);
digitalWrite(13, LOW);
Bridge.begin();
digitalWrite(13, HIGH);

bzero(buf, MaxBuf);
strcpy(buf, "Test >>orrtool");
orrtool.begin ("echo");
orrtool.addParameter(buf);
orrtool.run();

What I expect to see is a file called orrtool created on the Yun - doesn't happen - any ideas on what I'm doing wrong? I tried having the file be /tmp/orrtool and /mnt/sda1/orrtool - neither worked even if I touched and chmod'd them before running the above.

TIA

addParameter doesn't work with output redirection. You should use runShellCommand instead

Thank you, and Happy Holidays!
