Mais uma dica valiosa sobre editar o “Regedit” em varios computadores com o PowerShell

Fonte: http://blogs.technet.com/b/heyscriptingguy/archive/2012/03/17/edit-the-registry-on-multiple-remote-computers-with-powershell.aspx

One way to avoid this and to enable the ability to make changes on multiple machines is to turn the commands into a single line. It is then really easy to run the command by using the Invoke-Command cmdlet. To do this, I use the following steps:

  1. Use the Get-Credential cmdlet to retrieve cmdlets. Store the returned credential in a variable.
  2. Use the Invoke-Command cmdlet to run the command on remote computers.

The two commands are shown here. Keep in mind that the second command is one long command that has wrapped over several different lines. I have not included line continuation for this command.

$cred = Get-Credential iammred\administrator

Invoke-Command -cn dc3 -cred $cred {pushd;sl HKCU:\software; ni HSG; New

-ItemProperty -name forscripting -PropertyType string -path hsg -value “powershell rocks” ; popd}

The registry key is the same registry key and registry property that I created in yesterday’s blog. I test the command, and the commands and the output associated with the commands are shown in the image that follows.

Now, I decide to test the command against two computers. The only change required is to add an additional computer name to the –cn property (I deleted the registry key on DC3 prior to running the code the second time). This is shown here.

I decide to make one more test. I have a text file that contains the names of some of the servers on my network. The file is Servers.txt. Each line of the file contains a different computer name, as shown here.

I can use the Get-Content (gc is an alias) cmdlet to read the contents of the text file. Instead of specifying a particular computer name, I can use Get-Content to retrieve the computer names for me. The revised command is shown here.

$cred = Get-Credential iammred\administrator

Invoke-Command -cn (gc c:\fso\servers.txt) -cred $cred {pushd;sl HKCU:\software; ni HSG; New-ItemProperty -name forscripting -PropertyType string –path hsg -value “powershell rocks” ; popd}

The image that follows illustrates these commands, and the output associated with the commands.

Well, that is about it for today. Join me tomorrow when I will talk about testing for registry keys and deleting them.
