PowerShell Tip : How to copy a file remotely using WINRM

Today, we are going to see how to copy a file to remote destination using WINRM. Traditionally SMB Protocol (File Sharing \\Servername\C$) was used to transfer the files but nowadays you will find SMB Protocol disabled on some servers so you will require firewall changes to perform that.  On the other hand WINRM Protocol 5985 is mostly open for Powershell Remote sessions, so we will use that to transfer the files. Lets get started : Step 1 : Create a PS Session for that server  $Session = New-PSSession -ComputerName <ServerName> Step 2 : Use Copy-Item with -ToSession to transfer the file using WINRM Copy-Item -Path C:\Scripts\Amar\TestFile.txt -ToSession $Session -Destination "D:\" TestFile.txt file will get copied from local system to the D Drive of the remote server. Happy Learning :)

For one or the other reason we sometimes don’t like the "Red colored ERROR" which we used to get when we come across some error in powershell like below : So lets change this red color shown in the console, although its of no use(i.e technically speaking, it will work in the same way) but still just for learning purpose lets do it. In order to make this ERROR Foreground as any other color(over here green), write the below command in the Powershell console. $Host.PrivateData.ErrorForegroundColor = "Green" Output : Quite interesting right, Not only this you can change colors of several properties like Warning, Debug, Verbose etc. Just run  $Host.PrivateData | get-member Hope you all enjoy this Post, Do Like, Share and Comment if you have any suggestion or queries.

How Invoke-Command works

To know how Invoke-Command works remotely check the below image : Apart from this, lets talk more about Invoke-Command. If you run invoke-command locally will this DeSerialization, conversion to XML etc will happen? the answer is NO. Since you are running it locally all this process are not performed. Further a Deserialized object Type i.e. the data fetched remotely through invoke-command contains only few methods as shown in the below image. Hence suppose you are fetching service info using invoke-command remotely and storing the output in a variable, you won’t get methods to Start or Stop the service. Example : $Service = Invoke-Command -Cn “Test” -ScriptBlock {get-service bits} $Service will show the process details, but you can’t perfom $Service.Stop() or $Service.Start() since its the deserialized data. But you can perform like this : $Service = Invoke-Command -Cn “Test” -ScriptBlock {get-service bits | Stop-Service} This will do the task you are lo

Error Handling Tips in PowerShell

Hi Geeks, We all know the ways to handle error in scripting or programming languages i.e Try, Catch, Finally and so on. The same thing can also be done in PowerShell.
