title: Start shell script from jmeter in directory of jmx
body: <p>I have got a jmeter test that needs to run a shell script before it can start. The shell script lays in the directory of the jmx file. I use an OS Process Sampler to invoke the script, but the working directory is set to the bin/ folder of apache jmeter, and thus causing an error.</p>
  
  <p>Is there a property for the current directory where my jmx testplan is?</p>
  
  <p>apache jmeter 2.8
  on ubuntu 12.04</p>
