Powershell One Liners

Instead of making a post every time I stumble upon a cool powershell one liner, I'll combine them all in this post. If you have a better one liner for my tasks, please comment.


Kill a process by name (In this case Jenkins).
 Get-Process | ? {$_.Name -like 'JenKins' }  | Stop-Process

 Delete all Duplication Downloads (I usually run it first without the del paramaters)
 dir  -r  | ? {$_.Name -like '(1)' }  | del

Powershell 3, Where/ForEach hack - allowing you to specify properties sans an anonymous expression.
 dir  -r  | ?  Name -like '(1)' 

 Restart Explorer (often auto-hide of taskbar gets stuck, restarting explorer fixes it.)
Get-Process | where name -eq explorer  |kill ; explorer

 Find Who's hogging memory
 Get-Process | sort "VM" -Des | Select-Object -first 10

Set current time  forward 4 hours
 set-date ((get-date) + [TimeSpan]::FromHours(4.0))

 Get my son's age in weeks
 ((get-date) - (get-date 4/22/2010)).TotalDays/7

1-Liners relying on  Power Shell Community Extensions (pscx)

Load pscx
  Import-Module Pscx

Load the VS environment:
  Import-VisualStudioVars 2012

Put stuff on/off the clipboard:
  PS C:\hgs\igsmilebox> dir *ts | Out-Clipboard
  PS C:\hgs\igsmilebox> Get-Clipboard


Get Time since last reboot:

PS C:\Users\idvor_000\SkyDrive\Documents> uptime

Uptime                                                         LastBootUpTime
------                                                         --------------
6.19:20:27.1723192                                             4/27/2013 10:01:13 PM

Finding CLR exceptions without visual studio

(If you want to understand what exception code 0xe0434352 is, read this post ) Often exceptions are thrown and caught and you don't see them. You probably know how to debug this in Visual Studio, so let me show you how to do it in cdb. Sample Code: class Program { static void Main(string[] args) { foreach (var x in Enumerable.Range(0,2000)) { Thread.Sleep(TimeSpan.FromSeconds(1)); Console.WriteLine("Hello World"); ThrowAndCatchException(); } } private static void ThrowAndCatchException() { try { throw new NotImplementedException(); } catch(Exception) { } } } Output of the application: Hello World Hello World Hello World Nothing about an exception, but you're sure it's happening behind the covers -- fire up cdb: C:\Program Files\Debugging Tools for Windows (x64)>cdb -pn consoleapplication3.exe <SNIP> ModLoad: 000007fe`f7e90000 000007fe`f7eb4000 C:\Windows\Mi...

Why do I keep getting exception code e0434352?

If you want to know how to debug CLR exceptions using cdb then read this post . Exception code e0434352 is the exception code used internally by the CLR to represent most exceptions(*). Regardless of if you throw a System.NullReferenceException or a System.ArgumentException in C#, you'll throw a SEH exception e0434352 under the covers. A fun way to validate this theory is to watch what happens to the CLR exceptions settings in cdb. Fire up cdb, and see the state of clr exceptions: 0:000> .shell -ci "sx" findstr clr clr - CLR exception - second-chance break - not handled clrn - CLR notification exception - break - handled .shell: Process exited Now, set the exception handler for exception number e0434352 and recheck the value of the clr exception handler: 0:000> sxe e0434352 0:000> .shell -ci "sx" findstr clr clr - CLR exception - break - not handled clrn - CLR notification exception - break - handled .shell: Process exited Armed with ...

Powershell script to enable windows to capture localhost traffic in wireshark

If you want to understand why the following scripts work read this post . Otherwise just paste the following into an elevated powershell window: Setup windows networking to allow localhost capturing in wireshark: # Find the network configuration that has the default gateway. $defaultAdapter = Get-WMIObject Win32_NetworkAdapterConfiguration | ? {$_.DefaultIPGateway} if (@($defaultAdapter).Length -ne 1) {throw "You don't have 1 default gateway, your network configuration is not supported" } # Route local IP address via the default gateway route add $defaultAdapter.IPAddress[0] $defaultAdapter.DefaultIPGateway Write-Host "Start capturing on localhost by connecting to $($defaultAdapter.IPAddress[0])" Return windows networking to normal configuration: # Find the network configuration that has the default gateway. $defaultAdapter = Get-WMIObject Win32_NetworkAdapterConfiguration | ? {$_.DefaultIPGateway} if (@($defaultAdapter).Length -ne 1) {throw "Y...
