Features of CMD vs PowerShell
As we go further into using the command-line interfaces, we must be able to differentiate the various aspects between cmd vs PowerShell. These differences are not limited to their capacities but how they interpret orders, error handling, and sentence structures.
The critical difference between these tools is that you must choose one according to the nature of your task, irrespective of whether you are a systems administrator or just a developer.
Command Syntax:
If you have been using a Windows personal computer for some time, you will find that CMD uses almost similar syntax to DOS commands. They are simple but flexible and powerful, like PowerShell cmdlets.
However, PowerShell relies on a verb-noun structure when scripting its cmdlets. A simple look at a script is enough to determine why it is supposed to work. Likewise, the cmdlet Get-Process gets the process’s status on a computer system.
Scripting Capabilities:
While CMD allows for basic scripting capabilities using batch files (.bat), it is far less powerful and flexible than PowerShell. PowerShell uses scripts (.ps1) and comes with a fully developed scripting language. It supports variables, loops, conditions, and more complex programming constructs, making it much more potent for automation tasks.

Access to System APIs:
CMD only gets access to some system APIs, thus limiting what you can achieve. However, PowerShell can interact with the .NET framework and WMI fully, which gives it power over each feature of the Windows management system.
Pipeline Support:
Both CMD and PowerShell support pipelines, allowing you to pass the output of one command as input to another command. However, while CMD passes text between commands, PowerShell passes objects.
In PowerShell, pipelines are more potent because they pass objects instead of text between commands. This distinction enables access to the properties and methods of these objects, enhancing the overall power and functionality of pipelines.
Error Handling:
PowerShell’s try/catch/finally blocks offer robust error-handling capabilities, marking a significant improvement over CMD, which relies on basic error handling using error-level codes.
While CMD might be suitable for running simple commands and scripts, PowerShell offers much more power and flexibility for managing Windows systems. Whether you’re automating tasks or managing system configurations, PowerShell is generally the better choice due to its advanced features and capabilities.
Performance And Scalability
Performance and scalability are essential elements when running tasks through command-line interfaces. Execution speed or ability to handle multiple parallel commands execution is critical for solving a simple problem or complex large-scale task automation.
While CMD may have a slight edge in raw performance and resource usage, PowerShell’s scalability and advanced features make it a more powerful tool for most tasks, especially for large-scale operations and task automation.
Now, let us see the performance and scalability of CMD vs Powershell for different use cases. In looking at each of these factors, we’ll compare the performance of CMD to PowerShell, including speed, resource use and task automation.
- Performance: Regarding raw performance, CMD commands execute faster than PowerShell cmdlets. Because CMD is a more straightforward shell with less overhead than PowerShell, however, the difference in execution speed is usually negligible for most tasks.
- Scalability: In terms of scalability, PowerShell takes the lead, as it seamlessly integrates with the dotnet Framework and WMI and boasts advanced scripting capabilities. Therefore, it is smooth in the execution of complex orders as CMD does. Powershell scripts work well for managing a PC or a large network machine.
- Resource Usage: CMD uses less system resources compared to PowerShell. PowerShell’s advanced features and integration with the .NET framework require more memory and CPU power. However, this difference is usually not noticeable in modern systems with ample resources.
- Task Automation: PowerShell’s superior scripting capabilities make it a more efficient and powerful tool for task automation, especially for large-scale tasks. While you can automate tasks with CMD using batch files, PowerShell scripts offer more control, flexibility, and error-handling capabilities.
While CMD might have a slight edge regarding raw performance and resource usage, PowerShell’s scalability and advanced features make it a more powerful tool for most tasks, especially for large-scale operations and task automation.
Security And Permissions
Security and permissions play a pivotal role in ensuring the integrity and safety of your systems. CMD vs PowerShell offer different security and permissions control levels, which can significantly impact their usage in various scenarios.
While both CMD and PowerShell provide command-line access for user permissions and privileges, PowerShell offers more advanced security features like execution policies, secure input, extensive logging, and secure remote access. These features make PowerShell a safer choice for managing Windows systems.
From execution policies to logging capabilities and remote access, we’ll explore how these command-line interfaces handle security and permissions. Now, let us see the security features and permissions control offered by CMD vs PowerShell.
Execution Policy:
PowerShell has a built-in feature called execution policy that controls the conditions under which PowerShell loads configuration files and runs scripts. Execution policy stands as a crucial security feature that aids in preventing the execution of malicious scripts, a feature not present in CMD.
Access Control:
CMD vs PowerShell respect the user permissions and privileges the Windows operating system sets. However, PowerShell’s integration with the .NET framework provides more granular control over permissions when executing cmdlets or scripts.
Secure input:
As for PowerShell, it offers a reliable method of inputting sensitive data such as passwords with the help of the `Get-Credential` cmdlet that safely prompts users to specify credentials. There is no similar inbuilt feature for the CMD.
Logging:
PowerShell exposes rich logging capabilities to enable administrators to keep track of every executed command; this is important for auditing and troubleshooting purposes. CMD has minimal logging capacities.
Remote access:
PowerShell has a feature called PowerShell Remoting that allows administrators to run commands on remote systems securely. While you can run remote commands in CMD using tools like PsExec, PowerShell is more secure and adaptable than CMD Remoting tools.
While both CMD and PowerShell provide command-line access for user permissions and privileges, PowerShell offers more advanced security features like execution policies, secure input, extensive logging, and secure remote access. These features make PowerShell a safer choice for managing Windows systems.
