Get is a blockchain-powered social network that bridges the gap between centralized and decentralized data.
The “verb get” is a command-line tool that allows users to search and download app packages from the iOS App Store. The “Xcode Command Line tools download” is a command-line tool that allows users to search and download app packages from the iOS App Store.
Do you recall the days of the DOS dir command? What about the ls command in Linux? If that’s the case, Get-childItem is similar but more advanced.
We even have an alias for dir and ls in PowerShell. The Get-Childitem PowerShell cmdlet may enumerate registry keys and values, certificates in different certificate stores, and even Active Directory, to mention a few things.

To comprehend Get-Childitem, think of it as a combination of dir and ls, except instead of simply files, it enumerates a large number of items. You may use it by using the alias or the entire command name.
You may be certain that this command will function with your PowerShell version since it has been available since PowerShell v1.
The Get-ChildItem command traverses a tree.
A file system is organized in a hierarchy. It features a hierarchical system, with files contained inside folders and folders contained within directories. A file system works similarly to a tree. That tree has a trunk (say, C:) and “branches” that branch off of it (folders). We have a tree command, in fact.
PS> tree Folder PATH listing for volume HD Volume serial number is 0000007B 22DC:666C C:. modules AdsiPS 1.0.0.2 Public AWSPowerShell <SNIP>
This command may be pointed to either local paths on the local machine, a PowerShell remote scriptblock with Get-ChildItem inside of it, or a UNC path. They’re all the same. Perhaps I just want to get a list of all the files in the current directory.
PS> dir -Path . PS> Invoke-Command -ComputerName SERVER1 -Scriptblock { dir -Path . }
Providers for PowerShell
Microsoft realized that navigating this “tree” like structure of a file system could be applied to other systems as well. A file system “tree” has folders and files but a registry has keys and values while the certificate system in Windows has stores and certificates inside of those stores. Each of these specific areas can all be represented as a tree thus the PowerShell provider was born. Why all this talk about Providers for PowerShell? Because the Get-ChilldItem cmdlet is part of the *-Item cmdlets that interact with PowerShell drives that each provider exposes.
The Get-ChildItem cmdlet may produce any number of items on a PowerShell disk and enables you to handle each item using the pipeline or a foreach loop in PowerShell. It recognizes the idea of a PowerShell drive, which enables you to provide the path to a file system folder, a registry key, or a certificate store all in one command.
This command may enumerate the C: folder, the HKEY Current User hive, and the PowerShell certificate store, as seen below.
PS> Get-ChildItem -Path C: Directory: C: Mode LastWriteTime Length Name —- ————- —— —- d—– 7/2/2017 7:01 AM AppData d—– 4/25/2017 4:36 PM CheckPoint PS> Get-ChildItem -Path HKCU: Hive: HKEY_CURRENT_USER Name Property —- ——– BCD00000000 PS> dir -Path Cert: Location : CurrentUser StoreNames : {TrustedPublisher, ClientAuthIssuer, Root, UserDS…}
Filtering
The Get-ChildItem PowerShell command may not only get all items on a disk, but it can also filter the data using three parameters: Filter, Include, and Exclude. When it’s feasible, you should always utilize the PowerShell Filter parameter. This argument transmits the filter syntax straight to the provider. This style is substantially faster, however it is entirely dependent on the service being requested.
When searching files, for example, a Filter syntax of Name -eq ‘foo’ can be OK, but it won’t function at all when querying the registry since the registry provider doesn’t offer a filter!
PS> dir HKLM: -Filter “Name -eq ‘foo’” ls : Cannot call method. The provider does not support the use of filters. At line:1 char:1 + ls HKLM: -Filter “Name -eq ‘foo’” + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotImplemented: (:) [Get-ChildItem], PSNotSupportedException + FullyQualifiedErrorId : NotSupported,Microsoft.PowerShell.Commands.GetChildItemCommand
When everything else fails, the Include and Exclude parameters are always available.
This PowerShell command also contains a few of filesystem-specific options, such as Force, which outputs hidden files and folders, and File and Directory, which only detects files and folders. Get-Help or the Microsoft documents provide a complete discussion of Get-ChildItem.
Get-ability ChildItem’s to resolve paths when using the wildcard character is another great feature. A wildcard character in PowerShell normally indicates anything. If you want to view all files with the.txt file extension, for example, simply type *.txt and the path to the folder.
PS> Get-ChildItem -Path ‘C:*.txt’
Filtering by file characteristics is also an option. Maybe all we want to do is locate the read-only files in a folder.
PS> Get-ChildItem -Path C: -Attributes R -File
Summary
This is one of those PowerShell cmdlets that you’ll use again and again. You’ll probably use the FileSystem provider most of the time, but it’s essential to note that this cmdlet can do a lot more. It may be used to search for files, folders, registry keys, registry values, certificates, Active Directory users, machines, and even environment variables, functions, and more.
If you’re not sure, use Get-PSDrive to view a list of all the loaded PowerShell disks that Get-ChildItem can query.
