PowerShell Inventory Script


This piece of code snippet below will use PowerShell cmdlet to get Computer Name,PC Model, Serial Number and the current logged on user.      

Below are the one liner codes to get the Computer Name,PC Model, Serial Number and the current logged on user.

#Will select/get the computer name from WMI Object (win32_Computersystem)
get-wmiobject win32_computersystem | Select Name

#Will select/get the PC Model from WMI Object (win32_Computersystem)
get-wmiobject win32_computersystem | select Model

#Will select/get the serial number from WMI Object (win32_Computersystemproduct)
#I just notice that the IdentifyingNumber as it is named by MS is equal to the serial number of the PC
get-wmiobject win32_computersystemproduct  | select IdentifyingNumber

#Will select/get the currently logged on user from WMI Object (win32_Computersystem)
get-wmiobject win32_computersystem -computer . | select username        


Here's the whole PowerShell code, which will get the data and display the output in one line.

The .ToString will convert the variable to string, in order to remove the line feed from the variable.

It takes a couple of time to figured out how to get rid of the line feed from the write-host output.

$varPCModel= $PCModel.ToString()

The line feed or the "`n" will be replaced by a blank or empty character so that the variable can be displayed in one line together with any string specified on the write-host command.

$resultPCModel= $PCModel.replace("`n","")


==========================================

$computername = get-wmiobject win32_computersystem | Select Name |  ft name -HideTableHeaders | Out-String
$PCModel = get-wmiobject win32_computersystem | select Model | ft -HideTableHeaders | Out-String
$SerialNumber = get-wmiobject win32_computersystemproduct  | select IdentifyingNumber | ft -HideTableHeaders  | Out-String
$xUserName = get-wmiobject win32_computersystem -computer . | select username | ft -HideTableHeaders  | Out-String

$varCompName = $computername.ToString()
$resultCompName = $varCompName.replace("`n","")
write-host "Computer Name-: $resultCompName"

$varPCModel= $PCModel.ToString()
$resultPCModel= $PCModel.replace("`n","")
write-host "PC Model-: $resultPCModel"

$varSerialNumber= $SerialNumber.ToString()
$resultSerialNumber= $SerialNumber.replace("`n","")
write-host "Serial Number-: $resultSerialNumber"


$varUserName=$xUserName.ToString()
$resultUserName = $varUserName.replace("`n","")
write-host "User Name-: $resultUserName"

===========================================

Sample output of the above code:

Computer Name-: Workstation01
             
PC Model-: HP ENVY 700-215xt Desktop
       
Serial Number-: PHH317X97B
             
User Name-:TEMP-USER-VANITY



To get rid of blank spaces of write-host command between the specified string and the variable output, use code below.

===========================================

$resultCompName = "$("Computer Name-:") $($computername)"
write-host $resultCompName

$resultPCModel= "$("PC Model-:") $($PCModel)"
write-host $resultPCModel

$resultSerialNumber= "$("Serial Number-:") $($SerialNumber)"
write-host $resultSerialNumber

$resultxUserName= "$("User Name-:") $($xUserName)"
write-host $resultxUserName

===========================================

Sample output of the above code:

Computer Name-:
Workstation01



PC Model-:
HP ENVY 700-215xt Desktop



Serial Number-:
SERIAL-317X97B



User Name-:
LINX-USER




Hope this helps someone!!!

Copy a single file using robocopy

Copy a single file using robocopy from a local folder to a shared folder on the network.
A simple rule of thumb before any disaster strike, don't interchange the source and the destination.

If source and destination is mistakenly reverse, files might get overwritten. To avoid any loss of data do a test with a dummy file to ensure things work perfectly.
Robocopy [source][destination]   [file to be copied]
robocopy c:\local_c_folder  \\PC_network\shared_folder   file_to_be_copied_xx.txt
The command will be completed successfully provided the network access right has no issues.

Robocopy works quite good on large files. A simple copy or xcopy command will also work but the speed might vary.

Robocopy is free it can be accessed from command line. No need to install the resource kit tool if the operating system is Windows 7 or newer version.

Copy files with selected file extension using PowerShell and Robocopy:

$extension = ('.pdf', '.jpg', '.txt')
gci d:\WorkFolde…

WMIC get computer name

WMIC get computer model, manufacturer, computer name and  username.
WMIC is a command-line tool and that can generate information about computer model, its manufacturer, its username and other informations depending on the parameters provided.
Why would you need a command line tool if there’s a GUI to check?
If you have 20 or 100 computers, or even more. It’s quite a big task just checking the GUI to check the computer model and username.
If you have remote computers, you need to delegate someone in the remote office or location to check.
Or you can just write a batch file or script to automate the task.
Here’s the code below on how get computer model, manufacturer and the username.
Open an elevated command prompt and type:
wmic computersystem get "Model","Manufacturer", "Name", "UserName"
Just copy and paste the code above, the word “computersystem” does not need to be change to a computer name.
