PowerShell Get-TimeMachine?!

Well, I know what you’re thinking it is just click bait. but I want to assure you it is possible.

new-timespanYou could create this into a function but the magic is in the details of this one.

“New-TimeSpan” is a tool that has existed since 2.0 and before you start-sleep ever again, consider the possibilities if you can truly calculate the duration of start-sleep dynamically!

So I stumbled across this only due to the need to simulate a scheduled task/job quickly in an environment I had not the local privileges to ensure that I could create a scheduled job.

If necessary you could utilize this to create some uniformity in your daily duties, reminders, etc.


So Let’s see this tag team with Start-Sleep!

tagteam timespan

I included the variable to display how this works so well. you just define when you want the script to stop that same day. It will show an error if you did it differently.  However, as long as the values are a positive number and not a negative integer you have a timespan.

The last example is using it to control things in the future….essentially a PowerShell Time machine, please share any of your experiences in the comments or on Twitter.


so just know that time only flows in one direction. Trying to relive the past can cause you errors lol kind of ironic how that works outside the shell too. Don’t forget to visit other parts of the city. See ya around, and avoid cyclic redundancy errors!

Learning when and “Where”.

learning your way around the shell is really important. the “where-Object” is like the GPS of the pipeline and to elaborate on the pipeline a little is a one way train to get you to the solution you need.

here is an example.

where GPS

I set this to select the first one to help trim the image. There are 3 properties to navigate these service entries.

I used the pipeline to give you an example of the “|” pipeline so you can understand the flow of things. the object(s) are declared and sometimes processed before the pipeline. then more things can happen.

Look below for an example:

Where Turn by Turn.jpg

The pipeline is the directions in which you mold your data.  you put that with some select-object & other commands like format-list, ConvertTo-html, Export-csv, & Out-File.

So I can’t wait to see what you have waiting to travel down the pipeline! See you around the city!

PowerShell: Styling your Profile.

It may not be something we all wake up in the morning thinking about but to wake up and make your life just a bit easier is something we all think about. probably at more times through out the day.

The PowerShell profile that is going to be covered are both user based profiles.

One is the Shell Profile and the other is the ISE Profile.

both profiles are saved via the $profile defined path.


These are essentially scripts with your preferences, functions, load frequently used modules, favorite variables, and etc.

I have been in some interesting situations where I automated report building into functions. Load specific modules that I use daily and some routine $variables to load that are always the same.

imagine how much time saving it would be to have your cup of coffee sitting and waiting on you in the car already made? that is the advantage the PowerShell Profile provides. A series of tasks, preparations that come automatic every time you click the sweet PowerShell emblem.

if you have network mapped user home folder, your profile can follow you to any and every server/machine you work on.

experiment and have fun with making your life easier.

any questions or comments let me know how you use your $profile !

How do you Compare?

Most people throw things at a problem and see what sticks.

Is this a true “solution” or a makeshift glue that can come unraveled at any given moment.

apples to oranges

I think that when we compare we should understand what is needed and not needed, and really understand our options.

Understand the basics

This is an example of a variable with text defined. we want to look for the word Fruit.

PS C:\> $Apple = "Red Fruit, Green Fruit, Yellow Fruit"

PS C:\> $Apple -match 'Fruit'

PS C:\> $Apple | where {$_ -match 'Fruit'}
Red Fruit, Green Fruit, Yellow Fruit

PS C:\> $Apple -like 'Fruit'

PS C:\> $Apple | where {$_ -like 'Fruit'}


So it looks like “Like” doesn’t like to be used in the way you cognitively expect.

PS C:\> $apple -like '*Fruit*'

PS C:\> $apple | where {$_ -like '*Fruit*'}
Red Fruit, Green Fruit, Yellow Fruit

Well there is a trick to it. The trick is it has rules that govern how it looks at the compared objects and if it care about what comes before or after the string you are looking for.

I like to use match. some instances like the Active Directory module that comes with RSAT doesn’t allow it with the -filter parameter. you can pipe and filter instead.

Take a look below:

PS C:\> get-aduser -filter {givenname -like *Xajuan*}

VS the pipeline equivalent below:

PS C:\> get-aduser -filter * | where {$_.givenname -match

Either way stay true to your comfort zone and be sure to explore outside it, because at the end of the day, you got to get the job done, and nothing compares like that is complete.

Enabling Remote Desktop remotely with PowerShell — from SID-500.COM

Consider the following scenario: There’s a switched on client computer in a branch office and you want to connect to that computer via remote desktop. Remote desktop is disabled by default on all Windows operating systems. There’s no user logged on this client computer and no one can help you to enable remote desktop. What […]

Functioning like an Adult. (In the Shell)

functioning like an adult

I would like to propose we should all function as adults at some point in life. maybe not 24 hours a day but enough to take care of ourselves.

PowerShell is an area that need you to be functioning to preserve your sanity and time, I will cover simple & advanced functions.

A function can save you a ton of typing and it could do quite a bit and be called using the infamous tab completion!

Simple Function Example:

Function Test-Google
Try{ $result=Test-Connection google.com
if ($result -ne $null){ write-host "Google is up and reachable" -ForegroundColor Green} 
Catch{write-host "Google Error Occured" -ForegroundColor Red}



Advanced Function Example:

Function Test-NetworkConnectivity
[parameter(ValueFromPipelineByPropertyName,ValueFromPipeline)][Object[]]$Website =@( "google.com","Bing.com")

Try{ $result=Test-Connection -ComputerName $site
if ($result -ne $null){ write-host "$site is up and reachable" -ForegroundColor Green} 
Catch{write-host "$site Error Occured" -ForegroundColor Red}

Take the time to explore tab completion.  this advanced function has way more capability and any questions?



Eventfully Troubleshooting Desktop Issues.

in the event you need to check your computer events to track down issues with your machine I must implore you to use “get-EventLog”


use this to your advantage to pinpoint issues.


in the image I used :

Get-EventLog -LogName system -Newest 1 -EntryType Error | Format-List


mainly to for word wrap and readability you can also automate this and dump to a report or email every so often.



Audit Objects in your Domain(s) Ready to Switch?

I find it important to figure out who and what is in your active directory OUs

get-aduser $TargetedUser

What about groups, and computers?

get-adobject $targetObject

this includes users, groups, and computers.

here is a switch that will report differently based on object class property that gets returned.

get-adobject -filter *| foreach-object{
Switch($_.Objectclass) {

User{ write-host "Found a User" -foregroundcolor red
      $_ | export-csv Users.csv -notypeinformation -append
     } #end User

Group{ write-host "Found a Group" -foregroundcolor blue
       $_ | export-csv Group.csv -notypeinformation -append
     } #end group

Computer{ write-host "Found a Computer" -foregroundcolor cyan
          $_ | export-csv Computers.csv -notypeinformation -append
     }#end Computer
}#end switch

}#end Foreach-object from pipeline

Add-Member if you want to effectively “object” all things and possess their property.

I thought I would clarify this as most articles don’t simplify this to easily wrap you head around.

Add-member is what I would use to add a new member to a group of properties on an object

  1. I create the object
  2.  Add a noteproperty that translate to text
  3. create a scriptmethod that can do things based on a scriptblock when called.
  4. create a scriptproperty that runs each time you call the $x object to display the results of it’s script block.
Here is the code:
$x=new-object psobject
$x| add-member -name ID – value “smithx” -membertype Noteproperty
$x| add-member -name ADlookup -value { get-aduser $x.name } -membertype scriptmethod
$x|add–member -name ADinfo -value {$x.adlookup()} -membertype Scriptproperty

if you want you can overwrite a member with the -force command.

Try & Catching Errors so you can relax Finally.

Sometimes you gotta Try…. okay enough pep talk.

using the Try Command will allow you to catch any terminating errors. unless you specify for some commands you will not catch the errors and may not want to actually.


 Try{ get-childitem c:\incorrectlyspelledfolder\  -erroraction Stop -recurse -errorvariable ErrorCity}

#for every Try there must be a catch

Catch {write-host "Error: $($errorCity.gettype().fullname)"}

I wrote this to have the error show the  expression needed to catch specific errors you actually care about.

so you can to catches or specific instructions to go with specific errors. lie write this to one file and email the results on another catch instance.


get-childitem $folder -erroraction Stop -recurse -errorvariable ErrorCity -OutVariable Results 
 #for every Try there must be a catch #specific to error records now it will write the line.
catch [System.Management.Automation.ErrorRecord]{Write-host "Typo?"} #this catch will catch any other error like permission denied, etc. 
Catch {write-host "Error: $($errorCity.gettype().fullname)" -ForegroundColor Red} 

Finally{write-host "finished processing $folder " -ForegroundColor Green
        write-host "Sub Folders are :"
#finally is optional to do a set of command regardless of error on the object being processed.
Good Luck Trying & catching errors and finally understanding.
