Here is a list of Power Shell Scripts that are too cool to ignore

For the uninitiated:

Symbol	Meaning
%	shortcut for foreach object
$_	current object in the pipeline

List of AD accounts and the last time they logged in

Get-ADUser -Filter * -SearchBase "dc=home,dc=scotnpatti,dc=com" -ResultPageSize 0 -Prop CN,samaccountname,lastLogonTimestamp | select CN, samaccountname,@{n="lastLogonDate";e={[datetime]::FromFileTime($_.LastLogonTimestamp)}}

List Memory Installed

List object from Registry - namely version of .NET installed

gci 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP' | sort pschildname -des | foreach-object {$_.name; $_.GetValue("Version");}

Remote commands

Replace a string in a file using a regular expression

So I downloaded a bunch of files from "the way back machine" site and I needed to update the hard-coded links to be relative site links. The following little script did it for me.

{{{!#highlight powershell $files = ls Level*.html foreach ($item in $files) {

(Get-Content -path $item) | % { $_ -Replace '(https://web.archive.org/nebula/level)([0123456789]{2})/', 'Level$2.html' } | Set-Content $item

} }}}
