How to use the command Get-ChildItem (with examples)

The Get-ChildItem command in PowerShell is used to list items in a directory. It can be used to retrieve a list of files, folders, or a combination of both in a specified directory. This command is exclusive to PowerShell and is a versatile tool for navigating and managing directories.

Use case 1: List all non-hidden items in the current directory

Code:

Get-ChildItem

Motivation: This example is useful when you want to obtain a list of all the non-hidden items present in the current directory. It allows you to quickly view and navigate through the files and folders.

Explanation: The Get-ChildItem command without any arguments returns a list of all items in the current directory, excluding hidden items. The command Get-ChildItem with no additional arguments is equivalent to Get-ChildItem -Attributes !Hidden.

Example output:

    Directory: C:\Users\Username\CurrentDirectory

Mode                LastWriteTime         Length Name
----                -------------         ------ ----
-a---        17/02/2022     08:45            786 example.txt
d----        17/02/2022     08:46                subdirectory1

Use case 2: List only directories in the current directory

Code:

Get-ChildItem -Directory

Motivation: This example is useful when you specifically want to retrieve a list of directories present in the current directory. It allows you to focus on the folder structure without the distraction of individual files.

Explanation: The -Directory parameter limits the results to only directories (folders). When used with the Get-ChildItem command, it filters out files and displays only the directories present in the current directory.

Example output:

    Directory: C:\Users\Username\CurrentDirectory

Mode                LastWriteTime         Length Name
----                -------------         ------ ----
d----        17/02/2022     08:46                subdirectory1

Use case 3: List only files in the current directory

Code:

Get-ChildItem -File

Motivation: This example is useful when you want to retrieve a list of only files present in the current directory. It allows you to focus on individual documents or files without the distraction of directories.

Explanation: The -File parameter limits the results to only files. When used with the Get-ChildItem command, it filters out directories and displays only the files present in the current directory.

Example output:

    Directory: C:\Users\Username\CurrentDirectory

Mode                LastWriteTime         Length Name
----                -------------         ------ ----
-a---        17/02/2022     08:45            786 example.txt

Use case 4: List items in the current directory, including hidden items

Code:

Get-ChildItem -Hidden

Motivation: This example is useful when you want to retrieve a list of items in the current directory, including hidden items. Sometimes there are files or folders that are hidden from regular view, and this command allows you to access and manage those hidden items.

Explanation: The -Hidden parameter includes hidden items in the results. When used with the Get-ChildItem command, it displays all items, including both visible and hidden elements.

Example output:

    Directory: C:\Users\Username\CurrentDirectory

Mode                LastWriteTime         Length Name
----                -------------         ------ ----
-a---        17/02/2022     08:45            786 example.txt
d----        17/02/2022     08:46                subdirectory1
-h---        17/02/2022     08:50            512 hiddenfile.txt

Use case 5: List items in a directory other than the current one

Code:

Get-ChildItem -Path path\to\directory

Motivation: This example is useful when you want to list items in a directory other than the current working directory. It enables you to view and navigate through the contents of a different directory without changing the current working directory.

Explanation: The -Path parameter is used to specify the path to the desired directory. When used with the Get-ChildItem command, it retrieves the list of items present in the specified directory.

Example output:

    Directory: C:\Path\To\Directory

Mode                LastWriteTime         Length Name
----                -------------         ------ ----
-a---        17/02/2022     08:45            786 example.txt
d----        17/02/2022     08:46                subdirectory1
