    Hello Everyone,

    I am wondering what it would be the best way to achieve the following.
    To save the output of a command and being able to compare it at a later time to see if there is any diference between the running configuration and the one stored.

    What I have attempted so far was to do a export-clixml and then do a compare-object but this doesnt seem to work with the type of output i am getting from this command.

    The output generated by this cmdlet is in the following format:

    EnabledOnDirectAccess : False
    Farms : {}
    Zones : {}
    NeverLaunchThroughGateway : False
    Key : 18d0d30f-3843-4da3-9547-44a164210758
    Name : TransferNSGW
    Address :
    SessionReliability : True
    RequestTicketTwoSTAs : False
    SecureTicketAuthorityUrls : {,}
    StasBypassDuration : 01:00:00
    StasUseLoadBalancing : True
    Id : 18d0d30f-3843-4da3-9547-44a164210758

    thanks in advance

    I am using a similar way to check if a folder with installation files contains the expected files. I create a list with the relative path and file name and a hash value and compare it with the same list I created before and exported with export-clixml.

    Why shouldn't it work? If you'd show your code we might help.

    Hi, @jacobo
    If you want to compare the name of files existing in a specific folder, at 2 specific times, then, the simplest way is this:

    $1 = @(dir $folderA -file).fullname   # this is the reference object
    $2 = @(dir $folderA -file).fullname  # this is the difference object, computed at any later time
    diff $1 $2   # the difference between the 2 objects is computed, and presented on the display

    If you need to, you can use the -PassThru switch PARAMETER to keep processing the result, maybe, in a pipeline. Also, you don't need any further processing, after you grab the name of the files ( just compare them ).

    Maybe, you can apply the same technique to your problem.

    Thanks for your replies.
    As i posted in the first post, the output it generates this cmdlet get-stfstoreservice is shows a list of values.

    I run the saved config against the run config with compare-object without parameters i take the following output, but it doesnt show where the difference is.

    diff ((Import-Clixml .\gateway4.xml).gateways) (Get-STFStoreService | select -ExpandProperty gateways) 
    InputObject                                                                 SideIndicator                                                              
    -----------                                                                 -------------                                                              
    TransferNSGW                                                                =>                                                                         
    TransferNSGW                                                                < =     

    If i select particular properties, for instance i see they match and they are the same.

    diff ((Import-Clixml .\gateway4.xml).gateways) (Get-STFStoreService | select -ExpandProperty gateways) -Property key,id,EnabledOnDirectAccess -IncludeEqual
    key                                   id                                                    EnabledOnDirectAccess SideIndicator                        
    ---                                   --                                                    --------------------- -------------                        
    18d0d30f-3843-4da3-9547-44a164210758  18d0d30f-3843-4da3-9547-44a164210758                                  False ==                

    How i could run it so it goes thru all the properties and highlights those which are different?

    You could try this:

    $1=@(gc .\MyFirstExport.XML)
    $2=@(gc .\MySecondExport.XML)
    diff $1 $2

    Notice that the XML files are read as TXT.

    In the end it was managed using the following

    diff (((Import-Clixml .\gateway4.xml).gateways | convertto-json ) -split "`n" ) ((Get-STFStoreService | select -ExpandProperty gateways | convertto-json ) -split "`n")

    thanks everyone for the replies.
