How do I set the value in a command shell for dotnet core

Question

Running dotnet core command dotnet run in a command line I found this

You can opt out of telemetry by setting a DOTNET_CLI_TELEMETRY_OPTOUT environment variable to 1 using your favorite shell.

How do I set this variable?

Thanks for your time.

Solution 1

On Windows use

set DOTNET_CLI_TELEMETRY_OPTOUT=1

to avoid that telemetry data is sent by dotnet.exe in the current command line session.

Or use

setx DOTNET_CLI_TELEMETRY_OPTOUT 1

do disable this feature permanently.

Solution 2

To set environment variable only for current cmd session write set DOTNET_CLI_TELEMETRY_OPTOUT=1 or set DOTNET_CLI_TELEMETRY_OPTOUT=true (according to .NET Core Tools Telemetry)

To set environment variable permanently use setx instead of set.

Edit: For setx it has to be setx DOTNET_CLI_TELEMETRY_OPTOUT 1, and changes will only take effect when a new command window is opened - they do not affect the current CMD.

Developer Command Prompt is started with this .bat file: C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools\VsDevCmd.bat so you can edit it and add permanent changes.

Solution 3

In MacOS, use

echo "DOTNET_CLI_TELEMETRY_OPTOUT=1" | sudo tee -a /etc/environment

to add the variable setting to your environment.

For Bash on Unix-like operating systems (you can find out if you're using Bash by typing echo $SHELL in your terminal), you can do the following. Be aware that this only works pre-installation! To opt out after you've already installed the SDK, you have to set the environment variable, and then re-run the installer with this value set:

For temporary opt-out for your user (reverts when you close your terminal session):

Set the variable

DOTNET_CLI_TELEMETRY_OPTOUT=1

Test if variable was set correctly (should see a 1 output)

echo $DOTNET_CLI_TELEMETRY_OPTOUT

For permanent opt-out for your user

Open .bashrc in your text editor of choice (for Fedora the default is GNU Nano)

nano $HOME/.bashrc

Scroll to bottom of file. Add the following line

export DOTNET_CLI_TELEMETRY_OPTOUT=1

Save and exit (in GNU Nano, you can hit ctrl+x, and it will ask you to save). Then restart your terminal session.

 exec bash

Test if variable was set correctly (should see a 1 output):

echo $DOTNET_CLI_TELEMETRY_OPTOUT

set DOTNET_CLI_TELEMETRY_OPTOUT=1 -> WORKS However setx DOTNET_CLI_TELEMETRY_OPTOUT=1 -> DOES NOT

[Marquizzo]

Is there a way to get the value after using setx to confirm it was stored?

[ZenoArrow]

You can check the values using "set" (without quotes). Just enter set without trying to define an environment variable and you'll get the list of environment variables currently defined (including those defined using setx).

@HamzaAhmedZia lose the "=" for setx
