I think, powershell is the best way to do configurations you have to do once. Adding some links to global (top) navigation is one of them:

asnp microsoft.sharepoint.powershell
$w = get-spweb http://takana
$l = New-Object Microsoft.SharePoint.Navigation.SPNavigationNode("Smells like team spirit", "/pages/teamspirit.aspx")
$w.Navigation.TopNavigationBar.AddAsLast($l)

Feature receiver

The alternative is to create a web scoped feature and provide properties:

To add items to a list in bulk, or remove them in bulk. Well to do that you can use SPLinq, Server Object Model and … web.ProcessBatchData, which is the most effective. I did an experiment today. I created 1000 tasks in my task list three times and removed all items in three different ways and took time. First I put 1000 items with ajax and listdata.svc:

function pad(n) {
   if (n >= 10000) return n;
   if (n >= 1000) return '0' + n;
   if (n >= 100) return '00' + n;
   if (n >= 10) return '000' + n;
   return '0000' + n;
 }
var s;
var counter = 0;
var title = "task "
function foo() {
   counter++;
   if (counter > 10000) {
      window.clearInterval(s);
   }
   else {
      var value = {};
      value.title = title + pad(counter);
      createNewTask(value);
   }
}
s = setInterval(foo, 200);

Then I ran three different scenarios. Here is the resut for VMWare machine Windows Server 2008 R2, 4GB RAM, SharePoint 2010 SP1:

A tip for all who want to administer AD with powershell: Idera Powershell scripts. Just sign up and get the free scripts for AD, SQL, Exchange and Sharepoint. I personally prefer to user modules, so I change the file extension from ps1 to psm1 and then I can use import functions as modules. Here is a simple example for creating for domain users:

import-module .\New-IADUser1.psm1
function Add-User($name) {
    New-IADUser -Name $name `
         -sAMAccountname $name `
         -ParentContainer 'CN=Users, DC=contoso, DC=com' `
         -Password 'SvenskaAkademien1786' `
         -EnableAccount -PasswordNeverExpires
}
Add-User "user01"
Add-User "user02"
Add-User "user03"
Add-User "user04"

update 2012-03-15: nice script from Ryan

Ryan Dennis has created a very handy script for creating random users. In PowerShell v3.0 there is a cmdlet for creating users: New-ADUser. So the function above can be rewritten like that:

A funny powershell command I came upon today together with my colleague. Remove all your custom features (which start with something, say contoso):

Get-SPFeature 
       | Where { $\_.DisplayName.StartsWith("Contoso.") } 
       | ForEach { Uninstall-SPFeature $\_.Id -confirm:0 -force }

Have fun!

Today I have struggled with User Profile Service Application. I should have followed this awesome tutorial by ShareponitGeorge. And many thanks to my friend David for the great assistance! One important thing to beware about: Forefront Identity Manager Service must be running. Otherwise you don’t see the existing synchronization connections and you can’t add new connections. You can ensure that this service is running by running services.msc (just press Windows button and write services). Or you can do in powershell:

It is useful to warm up a site after app pool recycling or after a site creation in development environments. I found a very simple script which I made even simpler:

$url = "http://takana"
$wc = new-object net.webclient
$wc.credentials = \[System.Net.CredentialCache\]::DefaultCredentials
$wc.DownloadString($url) | out-null
$wc.Dispose()

For more sophisticated warmups Wahid Salemi provided an interisting script to warm up your Sharepoint. By the way. Let us save it as a powershell function. Take a look at sharepointryan’s functions. Let’s create a proper function of that:

In order to change port number for the Central Administration site, run this cmdlet:

Set-SPCentralAdministration -Port 1337

You can set any number between 1023 and 32767 except 443.

In Powershell you can easily get the permissions in a web or in a list:

$web = get-spweb http://contoso.com
$web.Groups | select Name, Roles > .\\Desktop\\webgroups.txt
$list = $web.Lists.TryGetList("Assets");
$list.RoleAssignments | select Member, RoleDefinitionBindings > .\\Desktop\\assets-roleassignements.txt
```To get all users in all groups run:

$web.Groups | Foreach { Write $_.Name; Write “————-”; $_.Users | Select Name; Write “”; Write "" }

Om man högerklickar och väljer “Run With Powershell”, är det bra om fönstret inte försvinner… Det hade varit bra med en funktion som pause… Här kommer väl till pass en egen pause.:

function Pause ($Message="Press any key to continue...")
{
  Write-Host -NoNewLine $Message
  $null = $Host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")
  Write-Host ""
}

man kan skapa en .bat-fil med olika powershell-anrop:

powershell.exe -Command "& {.\\Script1.ps1}"
