How can i verify if a user is root in a java application? Thanks

<pre class="prettyprint"><code>Process p = Runtime.getRuntime().exec("id -u") </code></pre> Keep in mind that the "root" user on a system may not be called <code>root</code> (although it's rare to change it), and it's also possible to alias it to another username. If the current user is root-like, the output will be <code>0</code>.

Easy. Just use <pre class="prettyprint"><code>System.getProperty("user.name") </code></pre>

Keep in mind that the "root" user on a system may not be called root (although it's rare to change it), and it's also possible to alias it to another username. If the current user is root-like, the output will be 0.
