Where can I learn about Bash scripts?

Beginners/BashScripting to get started.

Awesome Bash to go deeper.

How do I set a variable so that it can be read by subsequent scripts and tasks?

Define and modify your build variables in a script

Define and modify your release variables in a script

Q: I'm having problems. How can I troubleshoot them?

A: Try this:

  1. On the variables tab, add system.debug and set it to true. Select to allow at queue time.

  2. 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?

A: $(Build.SourcesDirectory) and $(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?

See Troubleshoot Build and Release.

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.

I use TFS on-premises and I don't see some of these features. Why not?

Some of these features are available only on Azure Pipelines and not yet available on-premises. Some features are available on-premises if you have upgraded to the latest version of TFS.
