FAQ PowerShell - Foreach vs Foreach-Object

Показать описание

Here is a basic overview of the difference between Foreach and Foreach-Object:

Foreach-Object works at the pipeline and processes each object one at a time. The variable you use to access the object in the pipeline is $_ or $PSItem (If you use PowerShell V3+) You also have the ability to add Begin and End scriptblocks to run commands before and after you process each object in the pipeline.

Foreach loads all objects of a collection into memory at once and then processes them.

Note: I didn't call out that Foreach-Object itself has an alias called foreach that can be used while in the pipeline. But alas, I did not remember that until after the video was published.

You could have mentioned foreach index tbh, it's an interesting subject, too.
It is usable when need to extract the index of current element to be either used in another array (this way you can loop multiple arrays at the same time from single loop) or to generate output. An example - to enumerate CPU core count, but with custom output.
