What is a pipeline?

A pipeline is a method for chaining together commands in a singl, allowing the output of one command to be used as the input for the next.

How do you add a pipeline?

You add one using |

Example: command1 | command2 | command 3

Use a pipeline to get the notepad service then stop it.

Get-Process notepad | Stop-Process

Not all commands can be piped. How can you check whether a command can be piped?

Use the get-help command. Under “-InputObject” it will say whether the command accepts pipeline inputs.

You want to find out if the get-process command accepts pipeline inputs. What command would you type?

get-help -name get-process -full

How many commands can you chain together via the pipeline?

as many as you want

In VS Code, if you only want to run a specific portion of your script, how do you do it?
