Mastering Windows PowerShell Scripting - Third Edition

Enumerating and filtering

Enumerating, or listing, the objects in a collection in PowerShell does not need a specialized command. For example, if the results of Get-PSDrive were assigned to a variable, enumerating the content of the variable is as simple as writing the variable name and pressing Enter:

PS> $drives = Get-PSDrivePS> $drivesName    Used (GB)    Free (GB)    Provider      Root----    ---------    ---------    --------      ----Alias                             Alias C          319.37       611.60    FileSystem    C:\Cert                              Certificate   \ Env                               Environment ...

ForEach-Object may be used where something complex needs to be done to each object.

Where-Object may be used to filter results.
