PowerShell - More Can Be Dangerous

You might know the more tool - when you pipe output to more, the output is displayed page by page.

PS> Get-EventLog -LogName System | more

However, more can be dangerous as you see here. You will not get any results for a long time, and your CPU load increases. The more tool first collects all results before it starts paginating it. This could take a long time and a lot of resources.

That's why you should avoid more and instead use Out-Host with the parameter -Paging:

PS> Get-EventLog -LogName System | Out-Host -Paging

You immediately see the benefit: results appear momentarily, and no additional CPU load is created.
