rename files snippet

I've got a group of people I work with who distributes executable files with _'s
appended to the filenames. This little snippet made short work of that!

$path = "\\server\share\folder"
dir $path -Recurse -Include *_ | % {
Rename-Item $_ $_.name.Substring(0,$_.name.length-1)
}

Line 1: Set the path to traverse. It can be local or a network share or any
other Powershell provider (like a Onenote notebook or Sharepoint site).

Line 2: Does a dir (aka Get-ChildItem) of the path, recursing into subfolders,
and only includes those files which end in a "_" character. Pass the results
into a foreach-object loop, abbreviated here by the % symbol.

Line 3: Inside the loop, rename each item (as indicated by the $_ automatic
variable). On each item, look at the Name property, and use the Substring
method on that name. We want the substring beginning at the first character
(first element in any array in Powershell is indicated by 0), and ending at the
Length of the Name minus one.
