Powershell: create FQDN's for servers in globalvariables.ps1

Hi,

I'm loading my globalvariables.ps1 in my $profile.
Now I'd like to have all my servers available with NETBIOS and FQDN, how can I achieve this?

To clarify, a piece of my globalvariables.ps1:

GENERAL ################################################################################################
$Global:DomainFQDN = $env:USERDNSDOMAIN

SERVERS ################################################################################################
$Global:SCCMSiteServer01 = 'SCCMSERVER'
$Global:ConnectionBroker01 = 'CONNECTIONBROKER'
#ADDING EXTRA SERVERS HERE

#FQDN
#FOR EACH SERVER, ADD A GLOBAL VARIABLE SERVER_FQDN, HOWTO DO THIS?
$Global:SCCMSiteServer01_FQDN =  ($SCCMSiteServer01 + '.' + $DomainFQDN))
$Global:ConnectionBroker01_FQDN = ($ConnectionBroker01 + '.' + $DomainFQDN)

Hi,

Please find following example. I suggest to name your server variables with some constant, I used MySpecialVariable_ prefix to distinguish them.

$Global:DomainFQDN="local"
$Global:MySpecialVariable_server01="srv01"
$Global:MySpecialVariable_server02="srv02"
$Global:MySpecialVariable_server03="srv03"


get-variable -scope Global | ? {$_.Name -like '*MySpecialVariable*' -and $_.Value -ne $null -and $_.Value -ne ''} | % {if (!(get-variable | ? {$_.Name -eq "$($_.name)_FQDN"})){New-Variable -Name "$($_.name)_FQDN" -Value "$($_.Value).$($Global:DomainFQDN)" -Force}}

get-variable -Scope Global | ? {$_.Name -like '*MySpecialVariable*FQDN'} | ft -AutoSize

Thanks! Would it also be possible to only make variablesFQDN for a specific list? Otherwise it might also create variables which are also defined in scope Global (which are existing and should not get the FQDN).

Thanks but that makes it though to remember/use those variables in a script. Couldn't you just define those variables
$variables = $.... the ones I need
then add them with FQDN?

Hi,

Do you have a list of those variables? In case you want variable names to be meaningful you can only prefix them for the script

#before
$Global:SCCMSiteServer01 = 'SCCMSERVER'
$Global:ConnectionBroker01 = 'CONNECTIONBROKER'
#after
$Global:AutoVar_SCCMSiteServer01 = 'SCCMSERVER'
$Global:AutoVar_ConnectionBroker01 = 'CONNECTIONBROKER'

#then
get-variable -scope Global | ? {$_.Name -like 'AutoVar_*' -and $_.Value -ne $null -and $_.Value -ne ''} | % {if (!(get-variable | ? {$_.Name -eq "$($_.name)_FQDN"})){New-Variable -Name "$($_.name)_FQDN" -Value "$($_.Value).$($Global:DomainFQDN)" -Force}}

That way you keep your name intact, variables are recognizable globally by prefix.
