<title>RExec Task</title>
</head>
<body>
<h2 id="rexec">RExec</h2>
<h3>Description</h3>
<p>Task to automate a remote rexec session. Just like the <code>Telnet</code> task, it uses
nested <code><read></code> to indicate strings to wait for, and
<code><write></code> tags to specify text to send to the remote
process.</p>
<p><strong>Note</strong>: This task depends on external libraries not included in the Apache Ant
distribution. See <a href="../install.html#librarydependencies">Library Dependencies</a> for more
information.</p>
<p>You can specify the commands you want to execute as nested elements or via the <var>command</var>
attribute, we recommend you use the <var>command</var> attribute. If you use the <var>command</var>
attribute, you must use the <var>username</var> and <var>password</var> attributes as well.</p>
<h3>Parameters</h3>
<table class="attr">
<tr>
<th scope="col">Attribute</th>
<th scope="col">Values</th>
<th scope="col">Required</th>
</tr>
<tr>
<td>userid</td>
<td>the login id to use on the remote server.</td>
<td>No</td>
</tr>
<tr>
<td>password</td>
<td>the login password to use on the remote server.</td>
<td>No</td>
</tr>
<tr>
<td>server</td>
<td>the address of the remote rexec server.</td>
<td>Yes</td>
</tr>
<tr>
<td>command</td>
<td>the command to execute on the remote server.</td>
<td>No</td>
</tr>
<tr>
<td>port</td>
<td>the port number of the remote rexec server.</td>
<td>No; defaults to <q>512</q> in Unix</td>
</tr>
<tr>
<td>timeout</td>
<td>set a default timeout to wait for a response, specified in seconds.</td>
<td>No; default is no timeout</td>
</tr>
</table>
<h3 id="nested">Parameters specified as nested elements</h3>
<p>The input to send to the server, and responses to wait for, are described as nested elements.</p>
<h4>read</h4>
<p>declare (as a text child of this element) a string to wait for. The element supports
the <var>timeout</var> attribute, which overrides any timeout specified for the task as a whole. It
also has a <var>string</var> attribute, which is an alternative to specifying the string as a text
element.</p>
<p><em>It is not necessary to declare a closing <code><read></code> element like for
the <code>Telnet</code> task. The connection is not broken until the command has completed and the
input stream (output of the command) is terminated.</em></p>
<h4>write</h4>
<p>describes the text to send to the server. The <var>echo</var> boolean attribute controls whether
the string is echoed to the local log; this is <q>true</q> by default.</p>
<h3>Example</h3>
<p>A simple example of connecting to a server and running a command.</p>
<pre><rexec userid="bob" password="badpass" server="localhost" command="ls"/></pre>
<p>The task can be used with other ports as well:</p>
<pre><rexec port="80" userid="bob" password="badpass" server="localhost" command="ls"/></pre>
