Set Permissions on Multiple Sites using PowerShell

These days I had a request to add an Active Directory group with Contributor rights on a SharePoint Site Collection. Since many sites had broken inheritance, using the UI was not an option so I created a small PowerShell Script that enumerates all Webs and if the Inheritance is broken, it adds the group with the specified Role.

Notes:

• The If command uses the $web.Url.Contains directive in order to modify the rights only on a subset of sites. If all Webs have to be crawled, use if ($web.HasUniquePerm -and $web.RequestAccessEnabled) instead.
• This script modifies permissions only on webs. Lists and Items with unique permission will not be touched.

if ((Get-PSSnapin -Name Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue) -eq $null)
{
 Add-PSSnapin Microsoft.SharePoint.PowerShell
}


$site = Get-SPSite -Identity "http://spdev/sites/SiteCollection"


foreach($web in $site.AllWebs)
    {

    if ($web.HasUniquePerm -and $web.RequestAccessEnabled -and ($web.Url.Contains("/SiteCollection/BU1") -or $web.Url.Contains("/SiteCollection/BU2")))
        {
            $account = $web.EnsureUser("Domain\QATeam")
            $role = $web.RoleDefinitions["Contribute"]

            $assignment = New-Object Microsoft.SharePoint.SPRoleAssignment($account)
            $assignment.RoleDefinitionBindings.Add($role)

            $web.RoleAssignments.Add($assignment)
        }
    $web.Dispose()
    }
$site.Dispose()

SharePoint Start Workflow on All Items of a List via PowerShell

To start a List Workflow in SharePoint on All Items of a list is a pain through GUI but it's a piece of cake in PowerShell. Note that the Workflow will not start instantly (as opposed to triggering through the UI) but in maximum 5 minutes because it's started through the SharePoint Timer Service.

#updated on 10/17/2013

# URL of the Site
$web = Get-SPWeb -Identity "https://sharepointsrv/site1"

$manager = $web.Site.WorkFlowManager

# Name of the list
$list = $web.Lists["Shared Documents"]

# Name of the Workflow
$assoc = $list.WorkflowAssociations.GetAssociationByName("On Item Created","en-US")

$data = $assoc.AssociationData
$items = $list.Items
foreach($item in $items)
 {
 $wf = $manager.StartWorkFlow($item,$assoc,$data,$true)
 }
 
$manager.Dispose()
$web.Dispose()

ls - no colors on Ubuntu

I have some older Ubuntu servers that don't display colors when executing the ls command over Putty. So I took a .bashrc file from a different Ubuntu server and copied over the relevant section that contains the ls --color command. After that I applied the ~/.bashrc file so I don't have to restart the session. This will set the foloring for grep and vi as well.

~$ vim ~/.bashrc

if [ "$TERM" != "dumb" ]; then
    eval "`dircolors -b`"
    alias ls='ls --color=auto'
    alias grep='grep --color=auto'
    alias fgrep='fgrep --color=auto'
    alias egrep='egrep --color=auto'
    alias vi='vim'

else
    alias ls="ls -F"
    alias ll='ls -alF'
    alias la='ls -A'
    alias l='ls -CF'
fi


~$ source ~/.bashrc
