Using Powershell to Bulk Update List Items on Workspaces

Often we are faced with situation where in we need to update certain list values to reflect new values 🙂 this time we had a requirement wherein we needed to replace item values in a list with an updated value, though there are many ways to do it for instance using sharepoint API or object model & use code to get it done 🙂 However interestingly we this time i thought of using powershell command to perform the same & i had to write a very small script to get the job done & here it goes

$sites = Get-SPSite ‘http://ServerName/PWA’ | Get-SPWeb -Limit All
Foreach($site in $sites)
{
$site.title

$list = $site.Lists.TryGetList(“Risks”)

#Get all items in this list and save them to a variable
$items = $list.items

Foreach($item in $items)
{
#If the “Column” column value equals “Specified Value” Update with new Value
if($item[“Column Name”] -eq “Specified Value”)
{
#Change the value of the “Column Name” column
$item[“Column Name”] = “New Value”
#Update the item
$item.Update()

#Use this Optional Code to add new column to current list

#$myField = $list.Fields.Add(“Test5”, “Text”, 0)

#$list.Fields[$myField].Update()

#Write-host -ForegroundColor green “Column has been added”

}

}
