Wide Load
Get a better view of the data you've asked PowerShell to fetch with the Format-Wide cmdlet.

If you've used PowerShell 1.0 for any length of time you are most likely comfortable with Format-Table and Format-List. Those cmdlets are great when you have several object properties to view. However, there may be times when you only need a single piece of information. Try this:
Get-service | Where {$_.status -eq "Running"} | Select Name
You'll end up with a long list which can be a nuisance. A better solution would be to get all the services in one screen without any scrolling. To accomplish that, use Format-Wide, which has an alias of fw. All you need to specify is a property name to display:
Get-service | Where {$_.status -eq "Running"} | format-wide Name
The default will be a two-column display which may be more than sufficient. But you can specify the number of columns:
Get-process | format-wide -column 3
Or if you prefer, you can let the cmdlet squeeze in as much information by using the -autosize parameter:
Get-process | format-wide -autosize
Like the other formatting cmdlets, you can create a complex pipelined expression:
dir $env:temp -rec | sort Extension | format-wide Name -groupby extension -autosize
This command is recursively listing the %TEMP% directory, sorting all of the files by extension. The file objects are then piped to Format-Wide, which groups the output by extension and autosizes the output. Depending on the filenames, some extensions might have three columns and some might have eight. But the end result is a concise listing without requiring you to scroll backwards through many pages.
The next time you have a lot of information to look at quickly, think wide load. For more information, look at the cmdlet's help.
