Functions vs Filters

In my previous entry, I referred to Rsbohn’s blog PowerShell $Profile and his function to slow down output

function slowly ($tempo=100) { process { $_; Start-Sleep -milliseconds $tempo}}

This is a good candidate for a FILTER. A filter is function that just has a process scriptblock. So you could have written his as:

filter slowly ($tempo=100) { $_; Start-Sleep -milliseconds $tempo}
