SharePoint One Liners in Powershell

The magic of Powershell lies in executing complex queries in a single line which might need many clicks from an User Interface. Below are a couple of one line codes in PowerShell for SharePoint.

1.What is the SharePoint Version
(Get-SPFarm).BuildVersion

Note: 15 means SharePoint 2013,14 for SharePoint 2010,12 for MOSS

3. Get the domain name that hosts apps in the entire farm
Get-SPAppDomain

4. Display all the managed accounts in the farm
Get-SPManagedAccount

5. Returns all servers in the local farm with SharePoint installed excluding Exchange and non Application server.
Get-SPServer | Where{$_.Role -ne "Invalid"} |sort Address

5. Get the total number of site count hosted in each content database in Farm. Returns the display in HTML format stored at c:\getDBSitecount.html"
Get-SPContentDatabase | ConvertTo-Html -Property Name,WebApplication,CurrentSiteCount|Out-File -FilePath C:\getDBSitecount.html

5. List the timer job running monthly and show the output in gridview
Get-SPTimerJob|?{$_.Schedule -like "month*"}|SELECT Name,Decription,Schedule|OUT-GRIDVIEW
