At the first step, we simply get the help information for the Get-Command cmdlet. This output is an object—performing a text lookup operation is best done when the output is text. Out-String converts this output into a plain string; the only issue is that the whole block of text is one single string. A text lookup this way may not be really helpful. We use the -String switch to break the large string into smaller pieces (paragraphs in this case). Next, we use the Select-String along with the keyword to select the string that contains our keyword.
