Installing PowerShell Core on macOS and Linux | Microsoft Docs

Posted by jpluimers on 2018/03/26

I forgot to blog about this before, but 2 months ago PowerShell core came available: [WayBack] PowerShell Core 6.0: Generally Available (GA) and Supported! | PowerShell Team Blog.

[WayBack] Installing PowerShell Core on macOS and Linux | Microsoft Docs is easy (one way is through homebrew:

$ brew tap caskroom/cask
$ brew cask install powershell

If you already installed a beta, then the steps are these:

PowerShell Core is sufficiently different from prior PowerShell versions to warrant a name change. This also makes it a lot easier to use them side-by-side.

Many other names (like posh, pcsh or psh) were considered, usually because of naming conflicts with existing tools (like posh) or easy confusion with existing shells (like pcsh and csh). A benefit on Linux/macOS is that it now ends with sh like virtually all other shells.
