To add print to the console in a PowerShell script, you can use the Write-Host cmdlet followed by the message you want to display in quotes. For example, you can write:
Write-Host "Hello, World!"
This will print the message "Hello, World!" to the console when the script is run. You can also use variables and concatenate strings to customize your output. Keep in mind that Write-Host is primarily used for displaying output to the console, and should not be used for processing or formatting data within a script.

How to output text to the console in a PowerShell script?

Here is an example:

This will output "Hello, World!" to the console when the script is run. You can also include variables or expressions within the Write-Host cmdlet:

What is the protocol for adding logging to a PowerShell script?
- Decide on the level of logging needed for your script - This could be basic logging for errors only, or more detailed logging for debugging and troubleshooting purposes.
- Choose a logging method - PowerShell offers various logging cmdlets such as Write-Output, Write-Host, Write-Error, Write-Verbose, and Write-Warning. You can also use the Start-Transcript cmdlet to capture all output from a script.
- Add logging statements throughout your script - Use the chosen logging cmdlets to log important information, errors, warnings, and debugging details at various points in your script.
- Customize your logging output - You can customize the output format of your logs by adding timestamps, additional context information, or formatting the output in a specific way that is helpful for troubleshooting.
- Consider where to store your logs - Depending on your needs, you can store logs in a text file, a database, or a centralized logging system for easier access and management.
- Test your logging - Before deploying your script, test the logging functionality to ensure that logs are being created correctly and contain the necessary information.
- Review and analyze logs - Once your script is running in production, periodically review and analyze the logs to identify any issues, monitor performance, and make improvements to your script.
