how to run a shell script from within a ss script?

When a certain condition is met, I want to run a shell script that I have put in the Screen Scraper main installation directory. So my ss script code would look something like this, inside a while loop:

if (counter == 15)
{
        session.logError("15 iterations reached. Running the shell script and then waiting for 2 minutes");
        [run myshellscript.sh]
        counter = 0;
        sutil.pause(120000);
}
else   
{
        session.logError("Everything fine. Waiting for 10 seconds"
        counter = counter + 1;
        sutil.pause(10000);
}

How can it be done?
