Refer to this code below:

call {your command}>tmpFile1
set /p myvar= < tmpFile1 
echo "##vso[task.setvariable variable=testvar;]%myvar%"

or

FOR /F "tokens=* USEBACKQ" %%F IN (`{your command}`) DO (

Answer 2

If using Azure CLI version 2.*, you can use a powershell command rather than batch script wizardry. Microsoft's documentation found here

For example if you needed access token to update azure database it would look like so:

$token= & az account get-access-token --resource=https://database.windows.net --query accessToken
Write-Output("##vso[task.setvariable variable=sqlToken;]$token")

Answer 3

I've got some trouble (error code 255) with

    FOR /F “tokens=* USEBACKQ” %%F IN (`az account get-access-token --resource=https://database.windows.net/ -query accessToken`) DO (
SET var=%%F
)
echo ##vso[task.setvariable variable=sqlToken;]%var%

So I used this (and that work for me)

for /f "tokens=1 USEBACKQ" %%F in (`az account get-access-token --resource=https://database.windows.net/ --query accessToken`) do echo ##vso[task.setvariable variable=sqltoken;]%%F

Answer 4

Inspired from the answer above but with some variation.

Works in an Azure CLI task on a Hosted Ubuntu agent in Microsoft DevOps as of July 2019.

This example runs an az command to fetch the full resource name of a storage account and sets it in the variable _StorageAccountNameVar for use in another pipeline task.

myvar=`az storage account list -g MyResourceGroup --query "[?contains(name, 'config')].name" -o tsv`
echo $myvar
echo "##vso[task.setvariable variable=_StorageAccountNameVar;]$myvar"
