Run Shell
Run a system shell command under linux.
Most commands require root, so be aware of that.
If Timeout is 0, the command will never time-out.
Store Output In is a variable name for the output (stdout) of the command.
Similarly, Store Errors In is for error output (stderr).
A result code of 256 indicates a technical failure executing the command, 257 indicates that the specified Timeout value was exceeded, 258 indicates the process was interrupted.
Any non-zero result code will cause the task to stop, unless Continue On Error is checked, otherwise the result code will be stored in %err.
