What is the PowerShell pipeline used for?

• A. To execute commands in parallel.
• B. To pass the output of one command as input to another.
• C. To manage network drives.
• D. To convert scripts to executables.

Answer: (B)

PowerShell pipelines are about chaining commands so data flows from one to the next. The essence is that the output produced by one command is fed directly into the next, allowing you to build complex operations by composing small, focused cmdlets. Importantly, the pipeline passes objects, not just text, so each stage can access and work with the full properties of those objects. This makes workflows like filtering, transforming, and selecting data straightforward and readable. For example, you can pull process information, filter to those using more than a certain amount of CPU time, and then pick just the fields you want to see, all in one line: Get-Process | Where-Object { $_.CPU -gt 100 } | Select-Object Name, CPU. Each step consumes the objects from the previous step and passes its output along, enabling progressive data shaping without manual parsing or reformatting. Parallel execution isn’t the default behavior of the pipeline; it processes data through the chain in sequence, though PowerShell does offer dedicated ways to run work in parallel when needed.
