Active Directory PowerShell

Great question: Can I Create Active Directory Users Based On Excel Input

https://gallery.technet.microsoft.com/scriptcenter/PowerShell-Create-Active-7e6a3978

Great question: How do I find all the attributes of my users in the Active Directory

First start by starting the Active Directory Module for Windows PowerShell

Get-ADUser -filter *

Problem is however if you get all the users using -filter * you are missing some attributes. So using a wildcard for the properties will return all.

Using OGV (Out-Gridview) you get a quick view report

Get-ADUser -filter * -properties * | ogv

NOTE: You can use the same format above for ad users, ad groups or ad computers

Get-ADComputerUser -filter * -properties * | ogv

Get-ADGroup -filter * -properties * | ogv

Get-ADUser -filter * -properties * | ogv

Hope that Helps, Happy PowerShelling

Parsing Log File with PowerShell

Interesting article

http://matthewyarlett.blogspot.co.uk/2014/11/quick-and-dirty-parsing-logs-with.html

here is the code for reference

# Set the path to the log files            
$path = "C:\Temp\Logs"            
# Get a collection of all the log files (anything ending in .log)            
$files = Get-ChildItem -Path $path -Filter "*.log"            
# Pipe the collection of log files to the ForEach-Object cmdlet             
# (the alias of ForEach-Object is %)            
$files | %{            
    # Call the OpenText method, to return a System.IO.StreamReader object            
    $file = $_.OpenText();            
    # Record the current line number (to use in the console output)            
    $lineNum = 1;            
    Write-Host "Checking file"$_.Name -f Yellow;            
    # Use the EndOfStream method (which returns true when you have reach the end            
    # of the file), read each line of the file.              
    while($file.EndOfStream -ne $true)            
    {            
        # Read the next line in the file            
        $line = $file.ReadLine();                    
        if($line -ne $null)            
        {            
            # Use the String ToLower and Contains methods to check for occurances            
            # of the strings (or values) you need to check the file for            
            # In this example, I'm looking for any instances of the text "error" or "exception"            
            if($line.ToLower().Contains("error") -or $line.ToLower().Contains("exception"))            
            {            
                # If the current lines contains a match, write the line number            
                # and line text out to the console            
                Write-Host "Line: $lineNum " -NoNewline -ForegroundColor Green;            
                Write-Host $line -f Red;            
            }            
        }             
        # Increment the line number            
        $lineNum++;                   
    }
