PowerShell vs. Command Prompt: a beginner’s guide

Command-line interfaces (CLIs) like PowerShell and Command Prompt offer ways to interact with a computer’s operating system through text-based prompts. 

Whether you’re an IT expert or simply a casual Windows user, you can use Powershell and Command Prompt to manage files and folders, clean up your disk and drives, edit users, and much more. But with more than one CLI option, it can be confusing for beginners to know which is the right fit. 

That’s why we’ve created this guide to help you understand the difference between Command Prompt vs PowerShell and the best ways to use them to automate admin tasks. Let’s get started!

What is PowerShell?

PowerShell is a task automation scripting framework that was originally designed for Windows environments but is now available across different platforms. PowerShell is a CLI that allows users to communicate with a computer’s operating system through text-based commands. 

CLIs are typically considered the opposite of GUIs, or graphical user interfaces (think of an icon-based home screen). While graphical interfaces are more user-friendly for everyday tasks and non-techy people, those who work in IT or tech often need the advanced capabilities that a CLI makes possible. 

How does PowerShell work?

Powershell has two main components:

1. A command line shell, which is the environment where users type and execute commands.
2. A scripting language, which allows PowerShell to run code as written by a programmer.

This dual nature means PowerShell can both execute individual commands and automate tasks using scripts. It integrates closely with the .NET framework, enabling access to system-level functions on Windows devices.

To simplify interaction with .NET and system APIs, PowerShell includes cmdlets (pronounced “command-lets”) — small, single-function commands that can be used on their own or combined into scripts. PowerShell includes a wide array of built-in cmdlets, and developers can create custom ones as well.

Why is PowerShell useful?

PowerShell’s flexibility and depth make it an essential tool for both system administrators and developers. It can automate everything from user management to software updates and service monitoring.

PowerShell interfaces easily with Component Object Model (COM) components and Windows Management Instrumentation (WMI) — technologies that allow scripts to interact with Windows services and devices. These capabilities let administrators pull system status, automate tasks based on conditions, and integrate with third-party tools, all from within a single script.

What is Command Prompt?

Command Prompt, or CMD, is the default command-line interpreter built into the Windows Operating Systems. It’s also commonly referred to as the Command Processor Shell. Like PowerShell, CMD is a command-line interface that allows users to interact with the operating system through text-based commands. 

CMD is rooted in the disk operating system, or DOS, that powered older PCs. Its command syntax has remained very similar, making it very familiar to Windows vets. 

How does Command Prompt work?

CMD allows Windows users to execute many different system-level tasks, such as managing files and directories, running programs, and performing network diagnostics. CMD also allows for “batch scripting,” which means that you can put in a series of commands at once in a batch rather than manually entering each command individually. 

While it doesn’t offer the same deep integration that PowerShell does, users can still utilize CMD to perform essential tasks on their computer. Because CMD is lightweight and fast, it can be the right choice for your average Windows user who isn’t looking to do anything intricate.

They may sound very similar, but PowerShell vs CMD are very different in practice. Let’s take a closer look at the differences between these tools.  

What is the difference between PowerShell and Command Prompt?

While PowerShell vs CMD are both command-line interfaces native to Windows operating systems, but they serve different purposes and vary greatly in capability.

CMD is a more basic and familiar tool, using syntax based on the older MS-DOS interpreter. It’s often used for running simple scripts, managing files and directories, or sequencing tasks in batch files. These batch scripts are commonly deployed to automate routine administrative tasks during off-peak hours.

PowerShell, on the other hand, is a more powerful and flexible scripting environment designed for advanced system administration and automation. It includes access to system services like Windows Management Instrumentation (WMI), and supports modern scripting through cmdlets and the .NET framework — capabilities that CMD lacks. In short, PowerShell is CMD on steroids.

PowerShell is also updated more frequently, while CMD has seen few updates over the years. On Windows 11 and later, PowerShell is now the default CLI — and thanks to backward compatibility, it can still run most CMD commands.

When should I use PowerShell?

The main question you need to ask yourself when considering whether you should use PowerShell or stick to CMD is “will CMD be powerful enough for this?”. CMD can easily handle system-level tasks like;

• Navigating directories
• Managinffiles and folders
• Running executable programs
• Viewing and configuring IP settings
• Checking network connections and diagnosing connectivity issues
• Managing system processes and services 
• Scheduling tasks
• Automating commands using batch scripts 
• And much more

If you’re unsure about trying PowerShell for the first time, consider starting with one of your existing CMD batch jobs and enhancing it with PowerShell cmdlets. 

With PowerShell, those “if only I could” moments become achievable. The problem most people have with using PowerShell is that it is so big. Its vast functionality can make experienced administrators feel overwhelmed at first. It is a lot more comforting to stick with what you know. But don’t worry—PowerShell doesn’t replace your knowledge; it adds to it.

Many people wonder what the difference is between a batch script vs PowerShell script. While batch scripting is not PowerShell’s native language, PowerShell builds on the capabilities of batch scripting without inheriting its limitations. 

That’s why, if you can handle the more complicated tech, PowerShell is usually the better option for scripting.

Is PowerShell harmful?

PowerShell in and of itself is not harmful. However, like any scripting language, PowerShell can be used maliciously on computers. There are worms and file-less malware that use PowerShell routines.

To combat some of the threats, Microsoft introduced security features in the PowerShell environment; one of which is Execution Policies. PowerShell Execution Policies give administrators control over what scripts can be run on a system. The default policy doesn’t allow for any scripts to be run, but there are also options to require scripts to be signed by a trusted publisher, or to run unrestricted, allowing any script to run.

Can I use PowerShell and CMD commands with Atera?

Absolutely! In Atera, the in-app Command Prompt function means that any technician can remotely send CLI commands to any end user machine. For tasks like caching recent commands, real-time sampling and output, adding extra security like auto-terminate or shut down policies, this is a great tool. You can find the “Command Prompt” function in the “Manage” section on your “Devices.”

You can also run PowerShell scripts from inside Atera, also found under “Manage” in “Devices.” These are a very flexible way to run scripts in your environment.
