Batch Script task
Azure Pipelines | Azure DevOps Server 2020 | Azure DevOps Server 2019 | TFS 2018 - TFS 2015
Use this task to run a Windows .bat or .cmd script. Optionally, allow it to permanently modify environment variables.
This task is not compatible with Windows containers. If you need to run a batch script on a Windows container, use the command line task instead.
For information on supporting multiple platforms, see cross platform scripting.
In Microsoft Team Foundation Server (TFS) 2018 and previous versions, build and release pipelines are called definitions, runs are called builds, service connections are called service endpoints, stages are called environments, and jobs are called phases.

test.bat at the root of your repo:
@echo off echo Hello World from %AGENT_NAME%. echo My ID is %AGENT_ID%. echo AGENT_WORKFOLDER contents: @dir %AGENT_WORKFOLDER% echo AGENT_BUILDDIRECTORY contents: @dir %AGENT_BUILDDIRECTORY% echo BUILD_SOURCESDIRECTORY contents: @dir %BUILD_SOURCESDIRECTORY% echo Over and out.

Where can I learn Windows commands?
How do I set a variable so that it can be read by subsequent scripts and tasks?
Q: I'm having problems. How can I troubleshoot them?
A: Try this:
On the variables tab, add
system.debugand set it to
true. Select to allow at queue time.
In the explorer tab, view your completed build and click the build step to view its output.
The control options arguments described above can also be useful when you're trying to isolate a problem.
Q: How do variables work? What variables are available for me to use in the arguments?
$(Agent.BuildDirectory) are just a few of the variables you can use.
Variables are available in expressions as well as scripts; see variables to learn more about how to use them.
There are some predefined build and release variables you can also rely on.
Do I need an agent?
You need at least one agent to run your build or release.
I'm having problems. How can I troubleshoot them?
I can't select a default agent pool and I can't queue my build or release. How do I fix this?
See Agent pools.
