PowerShell Cmdlet Deep Dive: Format-Wide
Welcome back to Wahmans PowerShell blog! Today, we are going to explore a simple yet visually powerful cmdlet in PowerShell: Format-Wide. According to Microsoft, Format-Wide "Formats objects as a wide table that displays only one property of each object."
This makes it a great tool when you want to view a large list of items quickly in a wide, multi-column style for easier scanning. It’s especially handy when working in the terminal and keeping things human-readable matters.
Getting Started with Format-Wide
Format-Wide is ideal for formatting and presenting data—not for converting or filtering it. You generally use it at the end of a pipeline to display just one property from a collection of objects.
Example 1: Display a List of Services
Let’s list all services by their display name. This basic example is great for beginners:
Get-Service | Format-Wide -Property DisplayName
This will output services in multiple columns, showing just their DisplayName.
Example 2: Display All Running Processes by Name
Get-Process | Format-Wide -Property Name -Column 4
Here, we specify -Column 4 to format the process names into four columns on the screen.
Example 3: Custom Object Formatting
$files = Get-ChildItem -Path C:\Windows -File
$files | Format-Wide -Property Name
This command lists files in the Windows folder and displays just their names. Very helpful when you only care about what’s in a directory and not the metadata.
Example 4: Using Format-Wide with ScriptBlock for Dynamic Display
1..10 | ForEach-Object { [PSCustomObject]@{ ID = $_; Square = $_ * $_ } } | Format-Wide { $_.ID }
In this more advanced use case, we create objects with two properties and then use a script block to dynamically display only the ID property in the output.
Tips When Using Format-Wide
- Use it only at the end of the pipeline: it formats data for display, not for further processing.
- One property only: Format-Wide is designed to show a single property.
- Combine with sorting: Use
Sort-ObjectbeforeFormat-Wideto organize your output better.
That’s all for today on using Format-Wide to clean up and enhance your PowerShell output. It may not be the most powerful cmdlet, but mastering display tools like this makes scripts more user-friendly and results easier to comprehend.
Happy scripting, and I will see you in the next post!
