# Xygeni CLI Operation Modes

Xygeni CLI has **different operation modes** depending on the **scope** of the scan.

{% hint style="warning" %}
It’s important to ensure that the **JAVA\_HOME** environment variable points to the directory where Java is installed, which may or may not be done automatically depending on your platform. Additionally, you need to make sure that the $JAVA\_HOME/bin directory is included in your system’s PATH so that you can access the Java executable from anywhere on your system. Please see [Xygeni CLI Prerequisites](/xygeni-scanner-cli/xygeni-cli-overview/xygeni-cli-prerequisites.md) for further info.
