The Group-Object cmdlet displays objects in groups based on the value of a specified property. Group-Object returns a table with one row for each property value and a column that displays the number of items with that value. If you specify more than one property, Group-Object first groups them by the values of the first property, and then, within each property group, it groups by the value of the next property. The hash table keys use case-sensitive comparisons and output a System. Hashtable object. The output is sent to the Sort-Object cmdlet, which sorts them by the count files found for the given extension. The empty Name represents directories. This example shows how to use script blocks as the value of the Property parameter. This command displays the integers from 1 to 20, grouped by odds and even. Beginning in PowerShell 6, Group-Object supports sorting of hashtable input by key values. The following example groups an array of hashtables by the value of each hashtable's weight key. This example displays the 1, most recent entries in the System event log, grouped by EntryType.

We can however make sure that it is, by specifying the CaseSensitive parameter. I have been using Windows PowerShell more these days.

GUIs such as Task Manager lack the ability to group columns or objects. Hence, one of the benefits of using a PowerShell script is that you can append a Group-Object clause, and thus get a more meaningful display of data.

Here is a parallel technique, which achieves a slightly different result by using Format-Table and its parameter -GroupBy:. Download your free copy of WMI Monitor.

So while we definitely improved readability, you could argue that the code is less optimal as it has to evaluate the entire list of users twice. But for our specific problem above, do we have any alternatives? Group-Object in PowerShell is an underestimated cmdlet which lets us solve the problem in a single command instead.

To find the number of services that are running, and support a stop command, use the Group-Object cmdlet and a script block. Unlike Group-Object , which creates a single table with a row for each property value, the GroupBy parameters create a table for each property value with a row for each item that has the property value. The parameter NoElement takes care of that and gives us a trimmed result. This technique is shown here. In its most basic form, the Group-Object cmdlet accepts a property from objects in a pipeline, and it gathers up groups that match that property and displays the results. Name Value.

Specifies the culture to use when comparing strings. This example uses the AsHashTable and AsString parameters to return the groups in a hash table, as a collection of key-value pairs. Note that this may not always give you the result you expect, so if any problems occur when formatting the keys I would suggest you make sure to return a custom string in the group condition instead. Using the CaseSensitive parameter lets us differentiate between them in the groups. An example of this is the grouping of numbers, as shown in the image that follows. The Group-Object cmdlet displays objects in groups based on the value of a specified property.
