Need Powershell Scripting Help

PowerShell Help
1

I have modified a script I found on the internet and everything works great except getting the DNS Server search order. It outputs to an excel file using the Export-Excel module and under the DNSServerSearchOrder Heading in the spreadsheet it shows System.String. If I run the command from the command prompt it outputs the DNS servers correctly. Below is the code, any help would be appreciated.

#This Script will find the System Info for local and remote computers.  
# The output displays Computername,IPAddress,NetworkAdapter,MACAddress,DHCPServer,OS,ServicePack, ComputerModel,Username,Domain,Uptime, TotalMem, FreePhysicalMem, RegisteredUser,NoOfProcessors, ProcessorName,ProcessorType

Pretty common “gotcha.” https://devopscollective.gitbooks.io/the-big-book-of-powershell-gotchas/content/manuscript/a-crowd-isnt-an-individual.html has some background.

Essentially, you’ve got an array, and there’s no way for an array (multiple values) to go into a single cell without some effor on your part. For example, from your line 75:

$array | select Computername,Domain,IPAddress,OS,ServicePack,Uptime,ComputerModel,NetworkAdapter,@{n=‘DNSServerSearchOrder’,e={$_.DNSServerSearchOrder -join “,”}},DHCPServer,MACAddress,SystemDiskSize/GB,SystemFreeDiskSpace/GB,TotalMem, FreePhysicalMem, RegisteredUser,Username,NoOfProcessors, ProcessorName,ProcessorType | Export-excel .\systeminfo.xlsx

What I’ve done there will turn the array (designated by the after String in the output you were seeing) into a comma-seperated set of values. E.g., a single string, which can go into a single cell. You may need to mess with that until you’re happy with the output, but it’s the general idea.

Thanks I understand the issue now.

I copied your code into the script and here are the formatting errors I recieved:

$array | select Computername,Domain,IPAddress,OS,ServicePack,Uptime,ComputerModel,NetworkAdapter,@{n='DNSServerSearchOrder',e={$_.DNSServerSearchOrder -join ","}},DHCPServer,MACAddress,SystemDiskSize/GB,SystemFreeDiskSpace/GB,TotalMem, FreePhysicalMem, RegisteredUser,Username,NoOfProcessors, ProcessorName,ProcessorType | Export-excel .\systeminfo.xlsx

The e= is underlined with the errors

Missing expression after ‘,’
Unexpected token ‘e=’ in expression
the hash literal was incomplete

The second close parenthesis after -join “,” is underlined with the error

unexpected token ‘}’ in expression

DHCPServer is underlined with the error

unexpected token ‘dhcpserver’ in expression

I have tried to fix formatting with no luck.

Thanks in advance

@{n=‘DNSServerSearchOrder’,e={$_.

should be

@{n=‘DNSServerSearchOrder’;e={$_.

I believe. This technique - called a custom property or calculated property - is included in the examples in the help file for Select-Object, if you’d like to examine that documentation for further examples of its usage. It’s also covered fairly extensively in “Learn Windows PowerShell in a Month of Lunches,” if you’ve an interest in really nailing the fundamentals.

Worked perfect!!!

I will check ot the PowerShell lunch training.
