The bash script also reads PowerShell switches, so you can use PowerShell switches with the script on Linux/macOS systems.
dotnet-install scripts perform a non-admin installation of the .NET SDK, which includes the .NET CLI and the shared runtime. There are two scripts:
- A PowerShell script that works on Windows. For installation instructions, see Install on Windows.
- A bash script that works on Linux/macOS. For installation instructions, see Install on Linux and Install on macOS.
.NET collects telemetry data. To learn more and how to opt out, see .NET SDK telemetry.
The intended use of the scripts is for Continuous Integration (CI) scenarios, where:
The SDK needs to be installed without user interaction and without admin rights.
The SDK installation doesn't need to persist across multiple CI runs.
The typical sequence of events:
- CI is triggered.
- CI installs the SDK using one of these scripts.
- CI finishes its work and clears temporary data including the SDK installation.
To set up a development environment or to run apps, use the installers rather than these scripts.
We recommend that you use the stable version of the scripts:
- Bash (Linux/macOS): https://dot.net/v1/dotnet-install.sh
- PowerShell (Windows): https://dot.net/v1/dotnet-install.ps1
Both scripts have the same behavior. They download the ZIP/tarball file from the CLI build drops and proceed to install it in either the default location or in a location specified by
By default, the installation scripts download the SDK and install it. If you wish to only obtain the shared runtime, specify the
By default, the script adds the install location to the $PATH for the current session. Override this default behavior by specifying the
-NoPath|--no-path argument. The script doesn't set the
DOTNET_ROOT environment variable.
The script doesn't add the install location to the user's
PATH environment variable, you must manually add it.
Before running the script, install the required dependencies.
You can install a specific version using the
-Version|--version argument. The version must be specified as a three-part version number, such as
2.1.0. If the version isn't specified, the script installs the
The install scripts do not update the registry on Windows. They just download the zipped binaries and copy them to a folder. If you want registry key values to be updated, use the .NET installers.

For internal use only. Allows using a different storage to download SDK archives from. This parameter is only used if --no-cdn is false. The default is
Specifies the source channel for the installation. The possible values are:
STS: The most recent Standard Term Support release.
LTS: The most recent Long Term Support release.

If set, the script won't perform the installation. Instead, it displays what command line to use to consistently install the currently requested version of the .NET CLI. For example, if you specify version
latest, it displays a link with the specific version so that this command can be used deterministically in a build script. It also displays the binary's location if you prefer to install or download it yourself.
Used as a query string to append to the Azure feed. It allows changing the URL to use non-public blob storage accounts.
Prints out help for the script. Applies only to bash script. For PowerShell, use
Specifies the installation path. The directory is created if it doesn't exist. The default value is %LocalAppData%\Microsoft\dotnet on Windows and $HOME/.dotnet on Linux/macOS. Binaries are placed directly in this directory.
Specifies a path to a global.json file that will be used to determine the SDK version. The global.json file must have a value for
Disables downloading from the Azure Content Delivery Network (CDN) and uses the uncached feed directly.
If set, the installation folder isn't exported to the path for the current session. By default, the script modifies the PATH, which makes the .NET CLI available immediately after install.
If set, the installer uses the proxy when making web requests. (Only valid for Windows.)
If set with
ProxyAddress, provides a list of comma-separated urls that will bypass the proxy. (Only valid for Windows.)
If set, the installer uses the credentials of the current user when using proxy address. (Only valid for Windows.)
Downloads the latest build of the specified quality in the channel. The possible values are:
GA. Most users should use
The different quality values signal different stages of the release process of the SDK or Runtime installed.
daily: The latest builds of the SDK or Runtime. They're built every day and aren't tested. They aren't recommended for production use but can often be used to test specific features or fixes immediately after they are merged into the product. These builds are from the
dotnet/installerrepo, and so if you're looking for fixes from
dotnet/sdkyou must wait for code to flow and be merged from SDK to Installer before it appears in a daily build.
signed: Microsoft-signed builds that aren't validated or publicly released. Signed builds are candidates for validation, preview, and GA release. This quality level is not intended for public use.
validated: Builds that have had some internal testing done on them but are not yet released as preview or GA. This quality level is not intended for public use.
preview: The monthly public releases of the next version of .NET, intended for public use. Not recommended for production use. Intended to allow users to experiment and test the new major version before release.
GA: The final stable releases of the .NET SDK and Runtime. Intended for public use as well as production support.

Installs just the shared runtime, not the entire SDK. The possible values are:

The parameter is optional and should only be used when it's required to override the operating system that is detected by the script.
This parameter is obsolete and may be removed in a future version of the script. The recommended alternative is the

For internal use only. Allows using a different storage to download SDK archives from. This parameter is only used if --no-cdn is true.
If set, the downloaded SDK archive is kept after installation.
If set, the downloaded SDK archive is stored at the specified path.

If not specified,
Install the latest long-term supported (LTS) version to the default location:
./dotnet-install.ps1 -Channel LTS
./dotnet-install.sh --channel LTS
Install the latest preview version of the 6.0.1xx SDK to the specified location:
./dotnet-install.ps1 -Channel 6.0.1xx -Quality preview -InstallDir C:\cli
./dotnet-install.sh --channel 6.0.1xx --quality preview --install-dir ~/cli
Install the 6.0.0 version of the shared runtime:
./dotnet-install.ps1 -Runtime dotnet -Version 6.0.0
./dotnet-install.sh --runtime dotnet --version 6.0.0
Obtain script and install the 6.0.2 version behind a corporate proxy (Windows only):

Set environment variables
Manually installing .NET doesn't add the environment variables system-wide, and generally only works for the session in which .NET was installed. There are two environment variables you should set for your operating system:
This variable is set to the folder .NET was installed to, such as
$HOME/.dotnetfor Linux and macOS, and
$HOME\.dotnetin PowerShell for Windows.
This variable should include both the
DOTNET_ROOTfolder and the user's .dotnet/tools folder. Generally this is
$HOME/.dotnet/toolson Linux and macOS, and
$HOME\.dotnet\toolsin PowerShell on Windows.
For Linux and macOS, use the
echo command to set the variables in your shell profile, such as .bashrc:
echo 'export DOTNET_ROOT=$HOME/.dotnet' >> ~/.bashrc echo 'export PATH=$PATH:$DOTNET_ROOT:$DOTNET_ROOT/tools' >> ~/.bashrc
There is no uninstall script. For information about manually uninstalling .NET, see How to remove the .NET Runtime and SDK.
