Powershell; Write a file and open it

I have found this code quite helpful in debugging - especially trying to look through a large xml schema file for a SharePoint list.

$fileName = "myFile.txt"

# Write some variable property to a file
$web = Get-SPWeb "http://blah.com"
$list = $web.Lists["My List"]
$list.SchemaXml > $fileName

# Open the file in notepad
 Start-Process notepad  -ArgumentList $fileName

SharePoint 2013: Error updating managed account credentials

I encountered the following message when trying to change a password for a managed account: Error deploying administration application pool credentials. Another deployment may be active. An object of the type Microsoft.SharePoint.Administration.SPAdminAppPoolCredentialDeploymentJobDefinition named "job-admin-apppool-change" already exists under the parent Microsoft.SharePoint.Administration.SPTimerService named "SPTimerV4".  Rename your object or delete the existing object. The error message is self explanatory - Rename your object or delete the existing object.  I choose the latter. Powershell to the rescue. $job = Get-SPTimerJob -Identity "job-admin-apppool-change" $job.Delete() Reset the password and all should be good.

I needed to move the second item to a new 'Update Item' shape in order for it to work. I order to get the workflow to deploy, I had to manually remove the 'duplicate' item from the serialized XML. Hooray!! It was then a simple matter of creating a new shape to update the 'duplicate' value.
