"Free online edition" ... "Details on last page."
The last page with type talks about registering the book. I registered the book and then realized that the online edition is just a 45 day trial of Safari. If you want to keep it, you have to pay $22.99 / mo. I got the book at my local B&N. I see online that I could have bought print + PDF for just $5 more. I would have paid $5 more to add the PDF, but it appears to be $39.95 if I buy it from you without buying the book from you.
PS Other than that, I am very highly impressed with PowerShell and this book about it.

10.4.3 Discussion |
In section 10.4.3 the two MultiplyInput... functions are given the same name. The first is named correctly, but the second should be name MultiplyInputComplex.

The last line of the script does not work.
Here's what will work:
Set-StrictMode -Version Latest
$path = (Resolve-Path C:\Windows\Help\mui\*\WindowsPowerShellHelp.chm).Path
& $path

Example code |
In the Sample code:
$helpMatches += "Suggestion: An alias for $($alias.Definition) is $($alias.name)"
Needs a newline character or the suggestion lines all run together.
This can be fixed by adding a newline character.
$helpMatches += "Suggestion: An alias for $($alias.Definition) is $($alias.Name)`n"
Cool example tool to learn with so its worth having around.

5th paragraph |
The script I downloaded from O'Reilly for recipe 3.11 (Add Custom Methods and Properties to Objects) will not resolve some paths and will fail if the user attempts to get the owner of an empty directory. This code will fix both issues:
function Get-Owner ([string]$dir = (get-location).path) {
$files = Get-ChildItem $dir
if ($files -ne $null){
foreach($file in $files) {
if ($file -ne $null){
$owner = (Get-Acl $file.PSPath).Owner # fixes path issue in original code
$file | Add-Member NoteProperty Owner $owner
$file
}
}
}else{
# get owner of an empty directory
$files = Get-ItemProperty $dir
$owner = (Get-Acl $dir).Owner
$files | Add-Member NoteProperty Owner $owner
$files
}
}

Working with any root and example 6-1 |
The whole of this section is about how to find the cube root etc for a number.
The section states that power shell does not support the cube root or similar and goes on to give a complex (but correct) formula. But that formula is not required and powershell can find the cube root or nth root of any number:
PS> #Cube root of 27
PS> [math]::pow(27,1/3)
3
PS> #Tenth root of 1024
PS> [math]::pow(1024,1/10)

"Example 15.6 illustrates working with a performance counter from a specific category."
Example 15.6 is for COM scripting, not performance counters. I guess the author meant to recipe 15.8.

$filename = (Resolve-Path $file -ErrorAction SilentlyContinue).Path |
Example 17-3, get-filehash.ps1, has these lines of code:
$filename = (Resolve-Path $file -ErrorAction SilentlyContinue).Path
...
$inputStream = New-Object IO.StreamReader $filename
In Powershell 2.0, when resolving remote UNC paths, the $filename variable is given a value in this format:
Microsoft.PowerShell.Core\FileSystem::\\server\share
This value can not be passed to the StreamReader constructor.
Instead, the ProviderPath should be used:
$filename = (Resolve-Path $file -ErrorAction SilentlyContinue).ProviderPath
This sets the $filename variable to the expected format:
\\server\share

Typo in code, in name of the $option param

Recipe 23.16, 3rd paragraph (Discussion) |
The discussion says:
To see whether you have removed the user successfully, see Section 23.18, "List a User's Group
Membership."
However the current solution is about ADDing a user to a group, not removing it. Therefore the discussion
should say "to see whether you have added the user successfully, ..."

The error in the book concerns the use of the continue statement when used with a label. The book has the text "continue :outer" when the correct usage should be "continue outer". The colon is only used when defining the label.
