Background jobs are very useful for commands that take long amounts of time to complete. A background job can be created on the local computer by using the Start-Job cmdlet.

There are several ways to control the flow of code within your powershell scripts. The if, for, and while statements are used to define conditions and the actions to happen when the conditions are met. In this blog I’ll focus specifically on the if statement.
