Detailed Description

Class Batch

This class provides various utility functions for managing processes, services, and environment variables within the Bearsampp application. It includes methods for finding executables by process ID, checking which process is using a specific port, exiting and restarting the application, managing services, and executing batch scripts.

Key functionalities include:

• Finding executables by process ID.
• Checking which process is using a specific port.
• Exiting and restarting the application.
• Managing services (installing, uninstalling, setting descriptions, etc.).
• Executing batch scripts with optional output capture and timeout.
• Refreshing environment variables.
• Creating and removing symbolic links.
• Retrieving operating system information.

The class utilizes global variables to access application settings and paths, and logs operations for debugging purposes.
