Using PowerShell Core on Windows, Linux and macOS

Windows PowerShell is nothing new. It has been along with Windows for many years. Honestly, I preferred to use CMD more than PowerShell due to the learning cost. In the past few years, under the leadership of Satya Nadella, Microsoft is becoming opened and creative. More and more tools and frameworks support Windows, Linux, and macOS, including Visual Studio Code, .NET Core, and PowerShell. It is so good to use one scripting language for all platforms.

Command Prompt vs. PowerShell

For someone who is familiar with Linux Shell, Command Prompt as a Windows command line tool is probably a nightmare. Let’s try some simple commands to compare Command Prompt and PowerShell on Windows.

Change directory

The ‘cd’ command cannot work for changing drives in Command Prompt.


We can go to the home directory with ‘~’ symbol in PowerShell.

PowerShell supports a variety of commands that are used on Windows, Linux, and macOS. There are no obstacles to get used to PowerShell. You don’t need to change your habit. PowerShell is similar to Linux Shell but better. I still remember the day that Linux Shell syntax made me a headache. With PowerShell, I can quickly write scripts for Linux and macOS.
