45 Commands: Linux/Bash to PowerShell (With Examples)

By Charles Joseph | Cybersecurity Advocate

PowerShell is a powerful scripting language and command-line shell developed by Microsoft, designed primarily for task automation and configuration management.

It’s built on the .NET Framework and utilizes a versatile scripting language called PowerShell Scripting Language (PSL).

With its ease of use, flexibility, and robustness, PowerShell has become an indispensable tool for system administrators and developers alike.

Why Use Powershell?

One of the main reasons you’d want to use PowerShell is its ability to seamlessly manage and automate tasks across different Microsoft platforms and services.

It can be used to interact with the Windows operating system, Active Directory, Exchange Server, Azure, and many other Microsoft technologies.

Moreover, PowerShell enables you to manage remote systems, execute commands in parallel, and perform complex tasks with just a few lines of code.

Its object-oriented nature allows for precise control over data manipulation, offering better error handling and output formatting.

The first version of PowerShell, 1.0, was released with Windows Server 2008, and its popularity grew steadily with each subsequent release.

In 2016, Microsoft made a significant announcement: PowerShell was going open source, and a cross-platform version called PowerShell Core was being developed.

This move aimed to expand PowerShell’s reach and usability beyond the Windows ecosystem.

PowerShell Core, built on the .NET Core framework, was first released in 2018 as version 6.0, offering support for macOS and
