Store a cmdlet s result value in a variable in Powershell

Question

I would like to run a cmdlet and store the result s value in a variable   For example  C  PS gt Get-WSManInstance -enumerate wmicimv2 win32 process   select Priority   It lists priorities with a header  The first one for example   Priority -------- 8   How can i store them in a variable  I ve tried    var Get-WSManInstance -enumerate wmicimv2 win32 process   select Priority   Now the variable is    Priority 8  and I wanted it to be 8   Question 2   Can I store two variables with one cmdlet  I mean store it after the pipeline   C  PS gt Get-WSManInstance -enumerate wmicimv2 win32 process   select Priority  ProcessID   I would like to avoid this    prio Get-WSManInstance -enumerate wmicimv2 win32 process   select Priority  pid Get-WSManInstance -enumerate wmicimv2 win32 process   select ProcessID

Use the -ExpandProperty flag of Select-Object   var Get-WSManInstance -enumerate wmicimv2 win32 process   select -expand Priority   Update to answer the other question   Note that you can as well just access the property    var  Get-WSManInstance -enumerate wmicimv2 win32 process  Priority   So to get multiple of these into variables    var Get-WSManInstance -enumerate wmicimv2 win32 process     prio    var Priority     pid    var ProcessID

Just access the Priority property of the object returned from the pipeline    var    Get-WSManInstance -enumerate wmicimv2 win32 process  Priority    This won t work if Get-WSManInstance returns multiple objects 2   For the second question  to get two properties there are several options  problably the simplest is to have have one variable  containing an object with two separate properties    var    Get-WSManInstance -enumerate wmicimv2 win32 process   select -first 1 Priority  ProcessID    and then use  assuming only one process    var Priority   and   var ProcessID   If there are multiple processes  var will be an array which you can index  so to get the properties of the first process  using the array literal syntax        so it is always a collection1     var     Get-WSManInstance -enumerate wmicimv2 win32 process   select -first 1 Priority  ProcessID    and then use    var 0  Priority  var 0  ProcessID   1 PowerShell helpfully for the command line  but not so helpfully in scripts has some extra logic when assigning the result of a pipeline to a variable  if no objects are returned then set  null  if one is returned then that object is assigned  otherwise an array is assigned  Forcing an array returns an array with zero  one or more  respectively  elements   2 This changes in PowerShell V3  at the time of writing in Release Candidate   using a member property on an array of objects will return an array of the value of those properties
