When is PowerShell not PowerShell? When its PowerShell v6.

This applies to beta 9 and later

Check a v6 instance

PS C:\Program Files\PowerShell\6.0.0-beta.9> $PSVersionTable

Name Value
 ---- -----
 PSVersion 6.0.0-beta.9
 PSEdition Core
 GitCommitId v6.0.0-beta.9
 OS Microsoft Windows 10.0.17035
 Platform Win32NT
 PSCompatibleVersions {1.0, 2.0, 3.0, 4.0...}
 PSRemotingProtocolVersion 2.3
 SerializationVersion 1.1.0.1
 WSManStackVersion 3.0

Now try and run PowerShell

PS C:\Program Files\PowerShell\6.0.0-beta.9> powershell
 Windows PowerShell

PS> $PSVersionTable

Name Value
 ---- -----
 PSVersion 5.1.17035.1000
 PSEdition Desktop
 PSCompatibleVersions {1.0, 2.0, 3.0, 4.0...}
 BuildVersion 10.0.17035.1000
 CLRVersion 4.0.30319.42000
 WSManStackVersion 3.0
 PSRemotingProtocolVersion 2.3
 SerializationVersion 1.1.0.1

You get your v5.1 instance! You HAVE to use pwsh

PS> exit
 PS C:\Program Files\PowerShell\6.0.0-beta.9> pwsh
 PowerShell v6.0.0-beta.9

PS C:\Program Files\PowerShell\6.0.0-beta.9> $PSVersionTable

Name Value
 ---- -----
 PSVersion 6.0.0-beta.9
 PSEdition Core
 GitCommitId v6.0.0-beta.9
 OS Microsoft Windows 10.0.17035
 Platform Win32NT
 PSCompatibleVersions {1.0, 2.0, 3.0, 4.0...}
 PSRemotingProtocolVersion 2.3
 SerializationVersion 1.1.0.1
 WSManStackVersion 3.0

The command to start PowerShell v6 on Linux is also pwsh.

This is wrong on so many levels that its difficult to explain. I know its supposed to enable the separation on v6 and any older versions in a side by side install but having to remember this adds another level of unnecessary thought to using PowerShell. I’ve been a big fan of PowerShell for over 12 years but v6 and the changes that are being made are in many instances a step backwards for an illusionary gain.
