Situatie

PowerShell is much more than a replacement for Command Prompt. It combines a command-line shell with a scripting language and an object-based pipeline, making it one of the most useful administration tools available on Windows.

Navigation and Files

Get-Location
Displays your current location.

Get-ChildItem
Lists files and directories.

Set-Location C:\Temp
Changes the current directory.

New-Item -ItemType Directory -Path C:\Temp\Test
Creates a directory.

Copy-Item
Copies files or directories.

Move-Item
Moves files.

Remove-Item
Deletes items. Use this carefully.

Processes

Get-Process
Displays running processes.

Stop-Process
Terminates a process.

Example:

Stop-Process -Name notepad

Services

Get-Service
Lists Windows services.

Start-Service
Starts a service.

Stop-Service
Stops a service.

Restart-Service
Restarts a service.

Example:

Restart-Service Spooler

Networking

Get-NetIPAddress
Displays IP configuration.

Get-NetAdapter
Lists network adapters.

Test-NetConnection google.com
Tests network connectivity and provides more diagnostic information than a simple ping in many scenarios.

Example:

Test-NetConnection server01 -Port 443

can test whether a specific TCP port is reachable.

System Information

Get-ComputerInfo
Retrieves extensive Windows and hardware information.

Get-CimInstance Win32_OperatingSystem
Retrieves operating-system information through CIM.

Getting Help

Get-Help

This is arguably one of the most important PowerShell commands.

For example:

Get-Help Get-Service -Examples

shows examples for the Get-Service cmdlet.

Discovering Commands

Get-Command

If you know roughly what you want to do but don’t know the exact cmdlet, Get-Command can help.

For example:

Get-Command *service*

The Pipeline

The real power of PowerShell becomes apparent when commands are combined.

For example:

Get-Service | Where-Object Status -eq "Running"

retrieves services and filters the objects to show running services. Unlike traditional shells that primarily pass text between commands, PowerShell passes structured objects.That difference is fundamental.
