The command "fly -t ${target_name} pipelines" is used in the context of the Fly CLI tool, which is a command-line interface for interacting with Concourse CI, a continuous integration and continuous delivery (CI/CD) platform.

Here is a breakdown of the command:

• "fly" is the Fly CLI tool.
• "-t" is a flag used to specify the target Concourse instance. The value ${target_name} refers to a variable placeholder that needs to be replaced with the name of the target Concourse instance.
• "pipelines" is a command that is used to list or manage pipelines in Concourse CI.

Essentially, the command is asking the Fly CLI tool to connect to the specified target Concourse instance (identified by ${target_name}) and display a list of pipelines configured in that instance. The pipelines may represent various CI/CD workflows, consisting of tasks, resources, and jobs that define how code is built, tested, and deployed.
