dnvm is the "dotnet version manager." Dnvm is a command-line interface for installing and updating different dotnet SDKs.

dnvm installs .NET SDKs to the dnvm home path, which is ~/.local/dnvm on Linux, ~/Library/Application\ Support/dnvm/ on Mac, and %LOCALAPPDATA%/dnvm on Windows. Dnvm lets you:

• Install the latest release from channels through the track command
• Update SDK versions through the update command
• Cleanup old SDKs through the prune command (see detailed documentation)
• Install specific SDKs through the install command.

The --help command can help you find more information on all available commands.

• Prune Command - Detailed explanation of how SDK cleanup works

The simplest way to use dnvm is to track a channel. Channels are of two types: named channels and versions. Named channels are things like latest, lts, and sts. These correspond to the support status of various SDKs. For example, lts always corresponds to the currently supported .NET LTS SDK, while latest means the newest non-preview SDK in current support, LTS or STS.
