&gt; +1.4.5.  exec(command, [output], [input], [envavp])
&gt; +
&gt; +   Executes an external command. The input is passed to the
&gt; +   standard input of the new process, if specified, and the output
&gt; +   is saved in the output variable.
&gt; +
&gt; +   Meaning of the parameters is as follows:
&gt; +     * command - command to be executed.It can include
&gt; +       pseudovariables.
&gt; +     * output - pseudovariable where to store the output from the
&gt; +       standard output of the command. Keep in mind that if this
&gt; +       parameter is set, the async paramater will not be taken in
&gt; +       consideration.

<p>Could you call this [stdin], [stdout]<br>
and can we also get [stderr] ?</p>
