Disable .NET telemetry

Overview

About this script

This script improves your privacy on Linux.

These changes use Linux system commands to update your settings.

.NET, previously known as .NET Core 1, is a free, open-source, and cross-platform developer platform that allows the creation of various types of applications 2.

The .NET Software Development Kit (SDK) includes a telemetry feature, enabled by default 3, that collects and sends usage data to Microsoft upon the execution of .NET Command-Line Interface (CLI) commands. This data comprises your operating system, hardware specifics, geographic location, and .NET usage/installation information 3. A fraction of this collected data is made publicly available at .NET CLI Telemetry Data | dotnet.microsoft.com.

This script sets the DOTNET_CLI_TELEMETRY_OPTOUT environment variable to 1, opting you out of the .NET telemetry collection 3. It is crucial to establish this setting prior to the .NET installation since the installation process also sends telemetry data 3.

This script uses Bash (Shell script) scripting language.
