Finding Standard Parameter Names in PowerShell

 

PowerTip of the Day, from PowerShell.com:

 

In a previous tip, we suggested you to use standard parameter names for your own functions. To get a feeling for what the parameter names are that built-in cmdlets use, here is some code that creates a list of them:

PS> Get-Command -CommandType Cmdlet | Select-Object -ExpandProperty Parameters |  ForEach-Object { $_.Keys } | Group-Object -NoElement | Sort-Object Count, Name -Descending

(...)

   68 Force

   67 Name

   54 InputObject

   54 Credential

   52 Path

   44 PassThru

(...)

“Find how many types of files you have in you laptop” using Powershell.

 

Hi

Today i was searching for one PDF file on my laptop and then I just thinks “How Many PDF files do i have?”, i have no idea, one way to find is go to windows search and find all .PDF files? but “how can i find this with powershell”

we can

let try it ..

Cmdlet Used: Get-ChildItem,Group-Object, Sort-Object

Command: $files =  Get-ChildItem -Path C:\Users\aman.dhally\Documents –Recurse

In $files variable i am saving the result of Get-ChildItem -Path C:\Users\aman.dhally\Documents –Recurse  command , Get-ChildItem in equal as DIR command and we are using –Path switch parameter to give the path of the folder in which we want to search for files, –Recurse means including sub folders.

lets run $files variable and see what it has stored

It showing the files and folders located in my “Document” folder

let filer the results

$files | Group-Object -Property Extension | Sort-Object Count –Descending

now pipe the $files variable to Group-Object cmdlet and the grouping Property is Extensions because we want to group files by there extensions, now piped the command to Sort-Object and we are sorting the results by Count,

Find the List of Installed software using WMI and PowerShell.

 

Hi,

how you find the which software is installed on your computer, most of users answered  in “Control Panel” , yes it is right . but, if you are creating an Inventory of which system have which software then it’s not so useful for admins.

lets use WMI to retrieve the list of Install list of Softwares:

Cmdlet used: Get-WmiObject, Select-Object, Sort-Object, Export-CSV

Command is:

   1: Get-WmiObject win32_Product  | Select Name,Version,PackageName,Installdate,Vendor | Sort InstallDate -Descending

using Get-WmiObject cmdlet we query the win32_Product class which have the information of list of all software installations. Then we piped the command to Select cmdlet and we are selecting Name, Version, PackageName and installation date of the softwares and then pipe the command to Sort-Object cmdlet and sorting the result to descending order which mean latest first.

let export the result to CSV for future reference using Export-CSV cmdlet.

   1: Get-WmiObject win32_Product  | Select Name,Version,PackageName,Installdate,Vendor | Sort InstallDate -Descending| Export-Csv d:\report.csv

 

all command is same but we piped the command further to Export-CSV cmdlet and saving the file to D:\ with name of Report.CSV

 

let see if this created a csv file .

yes, file is created lets open it!!!

Done !!! seems good isn’t.

 

Thanks for viewing
