In a previous tip you learned how you can convert raw CSV data from a console application such as driverquery.exe into real PS objects. Let's play some more.
Since the CSV data only returns the complete path to a driver (which is too long to display without being truncated), let's add a "calculated property". That's a hash table with two keys: Name and Expression.
The script block in Expression takes the long path name and extracts just the file name. Now we get valuable driver information that – due to its object nature – can easily be sorted as well:
PS> $col1 = @{Name='File Name' Expression={ Split-Path $_.Path -Leaf } } PS> driverquery.exe /v /FO CSV | ConvertFrom-CSV | Select-Object 'Display Name', 'Start Mode', 'Paged Pool(bytes)', $col1 | Sort-Object 'Display Name' Display Name Start Mode Paged Pool(bytes) File Name ------------ ---------- ----------------- --------- ACPI-Energieanze...
