| 11 | <h2><a name="rexec">RExec</a></h2>
|
|---|
| 12 | <h3>Description</h3>
|
|---|
| 13 | Task to automate a remote rexec session. Just like the Telnet task,
|
|---|
| 14 | it uses nested <tt><read></tt> to indicate strings to wait for, and
|
|---|
| 15 | <tt><write></tt> tags to specify text to send to the remote process.
|
|---|
| 16 |
|
|---|
| 17 | <p><b>Note:</b> This task depends on external libraries not included in the Ant distribution.
|
|---|
| 18 | See <a href="../install.html#librarydependencies">Library Dependencies</a> for more information.</p>

|
|---|
| 58 | <h3><a name="nested">Nested Elements</a></h3>
|
|---|
| 59 | The input to send to the server, and responses to wait for, are
|
|---|
| 60 | described as nested elements.
|
|---|
| 61 |
|
|---|
| 62 | <h4>read</h4>
|
|---|
| 63 |
|
|---|
| 64 | <p>declare (as a text child of this element) a string to wait for.
|
|---|
| 65 | The element supports the timeout attribute, which overrides any
|
|---|
| 66 | timeout specified for the task as a whole. It also has a <tt>string</tt>
|
|---|
| 67 | attribute, which is an alternative to specifying the string as
|
|---|
| 68 | a text element.
|
|---|
| 69 | </p>
|
|---|
| 70 | <i>It is not necessary to declare a closing <read> element like for the Telnet task. The connection is not broken until the command has completed and
|
|---|
| 71 | the input stream (output of the command) is terminated.
|
|---|
| 72 | </i>
|
|---|
| 73 | <h4>write</h4>
|
|---|
| 74 |
|
|---|
| 75 | <p>describes the text to send to the server. The <tt>echo</tt> boolean
|
|---|
| 76 | attribute controls whether the string is echoed to the local log;
|
|---|
| 77 | this is "true" by default
|
|---|
| 78 | </p>
|
|---|
| 79 | <h3>Example</h3>
|
|---|
| 80 | A simple example of connecting to a server and running a command.
|
|---|
| 81 |
|
|---|
| 82 | <blockquote><pre>
|
|---|
| 83 | <rexec userid="bob" password="badpass" server="localhost" command="ls"/>
|
|---|
| 84 | </pre></blockquote>
|
|---|
| 85 |
|
|---|
| 86 | The task can be used with other ports as well:
|
|---|
| 87 | <blockquote><pre>
|
|---|
| 88 | <rexec port="80" userid="bob" password="badpass" server="localhost" command="ls"/>
|
|---|
| 89 | </pre></blockquote>
