Creating Your First PowerShell Script Using PowerShell Core

In this hands-on lab, you will create a PowerShell script that outputs process information to a file. You will have to use the appropriate PowerShell commands to filter the processes that are consuming more than 2 MB of memory. Additionally, you will be required to output only the `WorkingSet` and `ProcessName` columns to the file. Once you've created the file, you can view the contents using the `Get-Content` cmdlet.

  1. Challenge

    Connect to the Linux VM and Create the File

    1. Use the public IP and credentials from the lab instructions page to connect to the VM:

      ssh cloud_user@<PUBLIC_IP>
    2. Use a text editor (e.g., Vim) to create a file named processinfo.ps1.

  2. Challenge

    Create the PowerShell Script

    1. Within the processinfo.ps1 file, type in the command Get-Process and store it in the variable $ps.
    2. Use pipelines to pass the output of Get-Process to Where-Object and only take the WorkingSet object type.
    3. Use pipelines again to pass the output of the WorkingSet object to Format-Table. Only output the WorkingSet column and the ProcessName column, and store everything in the variable $psinfo.
    4. Use pipelines one final time to output the file (using out-file) to a CSV file named processinfo.csv.
    5. Save the file and exit Vim (hint: enter :wq!).
  3. Challenge

    Run the Script and Verify the Contents

    1. Run the PowerShell script by typing in ./processinfo.ps1 from the same directory as the file.
    2. Open the file using the Get-Content cmdlet.
