Executing a System Call

In order to run a system call, you will use the "system" action. This action does not trigger a call the "system" OS function, but a call to popen/pclose which is supposed to be thread safe.

The command will be executed as "sh -c <command>". Pipes and redirections work well. The action is successful if the command return code is 0.
