Windows PowerShell Crash Course for SharePoint Administrators (MIT07) – my notes

Session: Windows PowerShell Crash Course for SharePoint Administrators  (MIT07)

Speaker: DON JONES (

  • Most of DOS and UNIX well known commands work in Powershell  (PS) (including the good old functionality of using TAB to complete partially typed commands)
  • Powershell drives – adapts all forms of storage into a powershell drive get –psdrive
  • Extending the commands available in Powershell by default (400 commands by default out of the box): PSSnapin (Old way) vs. Modules (new Way
  • IMPORTANT: there is only one Powershell environment. The modules or the snapins are not different environments of Powershell but just predefined command set extensions.
  • Almost every Microsoft product will come with it’s own Powershell predefined Module (or Snapin) (e.g. event Active Directory has it’s own PS module)
  • PSSnapin to add snap-ins in PS and use various commands of a particular environment (e.g. a powershell snapin for SQL server will let you type SQL commands in powershell)
  • PS is build around the idea of piping = like DIR | more
  • Each time a command is run, there is an invisible table, which is generated into memory. Using an XML configuration file, PS knows how to choose what to show on the screen (obviously not all the information would fit on the screen and a choice has to be made)
  • ALL PS commands start with a verb: get, set, new, move, remove (-service, -process, -comand, etc)
  • For SharePoint, PS commands start with ‘sp’.  For SQL, PS commands start with ‘sql’; Exception is Exchange as it was the first product out on PS…well done Exchange guys 🙂
  • HELP on Powershell
    • ‘-full’ provides full help including usage examples for all commands.
    • “help * event *” will list all powershell commands or help files containing events
    • If there is a space in one parameter value you can use either ‘ or “ to include the value. Both work.
    • what if” parameter simulates the command and displays you the result without actually doing it
    • “-confirm” parameter ask you for a confirmation for each action needed for the command to complete
    • Unlike in UNIX, Powershell user does not have to process the output text of the command. Instead the user can ‘tell’ powershell how and what you want to look like (e.g. sorting a only have to know the name of the column and PS will display for you the results sorted on that column)
    • Pipeline input parameters (fastest way to make things happen): get –service –name bits | stop-service  (this will return the service which will be fed as parameter for stop –service command)
      • Another example: import-csv  ./users.csv |new –user (given the csv has the column names maching the command parameters names)
  • Remote Control
    • Requires PSH v2
    • ‘enter –pssession – computer server-r2’ will get us on the remote server-r2 (given we have access); “exit-pssession” to get out of it
    • You can import a remote set of commands not available on the local session (what happens is not a real import of commands but rather like a shortcut to the commands – if used such an ‘imported’ column it actually runs on the remote computer
    • 1:1 or 1:N remoting:
      • Enter-PSSession –computername X
      • Exit-PSSession
      • Invoke Comand – scriptblock {commands}
      • For SharePoint make sure you have granted shell administrator rights!
