<script type="text/x-red" data-help-name="watch">
|
||
<p>監視目錄或文件中的更改。</p>
|
||
<p>您可以輸入用逗號分隔的目錄和/或文件的列表。您需要在所有帶有空格的地方加上引號“...”。</p>
|
||
<p>在Windows上，必須在任何目錄名稱中使用雙反斜杠<code>\\</code>。</p>
|
||
<p>實際更改的文件的完整文件名將放入<code>msg.payload</code>和<code>msg.filename</code>中，而監視列表的字符串化版本將在<code>msg.topic</code>中返回。</p>
|
||
<p><code>msg.file</code>僅包含已更改文件的短文件名。<code>msg.type</code>更改了事物的類型，通常是<i>file</i>或<i>directory</i>，而<code>msg.size</code>保留了文件的大小（以字節爲單位）。</p>
|
||
<p>當然，在Linux中，<i>everything</i>也是一個文件，因此可以監視</p>
|
||
<p><b>注意：</b>該目錄或文件必須存在才能被監視。如果文件或目錄被刪除，即使重新創建它也可能不再被監視。</p>
