Install PowerShell Core on Ubuntu / CentOS using package management

Microsoft has release latest bits of PowerShell core and published PowerShell Core 6.0 alpha.15 to So we can use package management tools like yum or apt-get to install the latest PowerShell version on Linux distributions. It’s as simple as registering the Microsoft repository once as superuser and then just need to use either sudo apt-get install powershell or sudo yum update powershell (depending on which distribution you are using) to update it

Once you done this, you can use built in $PSVersionTable to confirm that its working properly:

Checking for PowerShell core version on CentOS

Or you can also use which command in linux to check if its installed. To get back to bash/login shell, type exit from PowerShell prompt.

Also, even if this is an alpha release, tab completion for cmdlet works. Intellisense works in more or less the same way as linux distributions. For example, if you type Get-ChildItem – and then press tab for getting parameters, nothing comes out. But if you press tab twice, it will list all parameters. Again, if you type the partial name of parameter, press tab twice to list it:
