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.

Table of Contents

  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.
