Basic Usage of LS Command

To start, open PowerShell and type ls followed by Enter. This will display the contents of the current directory. For a specific path, use:

ls C:\YourFolder

📌 Note: The ls command is case-insensitive, so ls, Ls, or LS all work the same.

Advanced LS Command Options

PowerShell’s LS command offers several parameters to customize output. Here are some commonly used ones:

• -Recurse: Lists files and directories recursively.


• -Force: Includes hidden and system files in the output.


• -Name: Displays only file and directory names, excluding details.

Example: ls -Recurse -Force C:\YourFolder

• ls -Filter .log: Lists all log files.

📌 Note: Wildcards like and ? can be used for flexible filtering.

Combining LS with Other Commands

The true power of PowerShell lies in combining commands. For example, pipe the output of ls to Select-Object for advanced filtering:

ls | Select-Object Name, Length

This command lists file names and sizes, demonstrating how to integrate LS command with other PowerShell functionalities. (Command Piping, PowerShell Integration, Advanced Scripting)

LS Command in Scripts

Incorporating the LS command into scripts automates repetitive tasks. For instance, a script to list all files in a directory and its subdirectories could be:

ls -Recurse C:\YourFolder | Export-Csv -Path output.csv -NoTypeInformation

This exports the list to a CSV file, showcasing the command’s utility in automation. (PowerShell Scripting, Automation, CSV Export)
