Objects, Properties and Methods Part 2

Let’s take a look at some examples using Methods:

We’re going to be using get-process and the process named notepad

  • First let’s open notepad, open your search bar and press notepad, minimize to the taskbar
  • Type get-process, press return, press return again. Scroll up, and we see that notepad is running. Press return and cls.
  • Type get-process -name notepad press return, now press return again

In our boat and car illustration we showed you that objects contain properties and methods, but when we take a look at get-process there are no methods or properties listed.

So, the question is, how can I display the property or methods for get-process?

  • By using a special command called get-member. We’ll use the alias gm for get-member.
  • Type get-process -name notepad | gm. (Use pipe operator) That’s the symbol right above the enter key. Press your shift key and your pipe operator.

If you recall, a pipeline takes the output of one command and pushes it through to the input of the second command. 

So, get-process has a process called notepad, and you’re piping the output of notepad into the input of get-member. Press return

  • There is some very important information, when using get-member. 

It’s TypeName. Typename tells us what kind of object that is being sent across the pipeline. In this case the TypeName is System.Diagnostics.Process but we’ll just use the last part which is process. Just keep that in mind, you’ll need it later when we get to the pipeline lecture.

  • Notice the method called kill. Kill is definitely an action.

Go ahead and type this out then we’ll explain it

  • Type (Get-Process Notepad).kill() 
  • To use a method of an object, Place the cmdlet name and the argument in parenthesis, then type a dot (.), then the method name, and a set of parentheses "()". 

The parentheses are required for every method call, even when there are no arguments.

The point is that we don’t need a separate cmdlet to close the process notepad we have the method kill. Press return

And we see that notepad has been closed.

Let’s try another example of using Methods

  • Let’s say we want to copy files from one location to another. In this case we’ll use the get-childitem command.
  • Let open windows explorer, for demonstration purposes I’ve created a folder named content. 

Double click on content and we have a text file named computers. click that file and displayed is the contents of the text file. 

  • Now we want to copy this file from the C:\content folder to the c:\test folder using a method called copyto.

Type get-childitem | GM – (Pipe operator) press return

Notice the get-childitem TypeName: is FileInfo 

We’ll use the copyto method to copy a file from one location to another

  • We don’t need a cmdlet, not when we have the copyto method, press return

Let’s go ahead and type the command then I’ll explain it.

Type (Get-childitem C:\content\computers.txt). copyto("C:\test\computers.txt") 

  • Put the cmdlet name and the argument in parenthesis then type a dot (.), the method name, in this case is copyto. and a set of parentheses "()".
