Analyze each component individually and understand its purpose before reassembling the pieces. This step-by-step approach will help you grasp what the entire script does and enable you to learn more efficiently.

For example, suppose you encounter the following script:

Get-Process | Where-Object { $_.CPU -gt 50 } | Sort-Object -Property CPU -Descending | Select-Object -First 5

Don’t panic! Remember, break it down:

1. `Get-Process`: Retrieves information about running processes.
2. `Where-Object { $_.CPU -gt 50 }`: Filters processes with CPU usage greater than 50.
3. `Sort-Object -Property CPU -Descending`: Sorts the filtered list by descending CPU usage.
4. `Select-Object -First 5`: Selects the top five processes with the highest CPU consumption.

By examining each part, you’ve gained a better understanding of the entire script.
