[MaximoTrinidad]

Steps to reproduce

After installing deb package, type 'pwsh'.

maxt@ubuntu:~$ pwsh

Command 'pwsh' not found, did you mean:

  command 'wsh' from deb wcc
  command 'ppsh' from deb ppsh
  command 'posh' from deb posh
  command 'pdsh' from deb pdsh

Try: sudo apt install <deb name>

maxt@ubuntu:~$

Expected behavior

type: pwsh, then will open PowerShell Core.

Actual behavior

pwsh can't be found to execute

Workaround

Type the full path:

/opt/microsoft/powershell/6-preview/pwsh

Hi @MaximoTrinidad ! Did you try what was listed in the release notes?

Note: In order to be able to deliver the PowerShell Core preview release and not deliver it to users expecting the stable release, we have renamed the preview package to powershell-preview and allowed it to be installed side by side with the stable package. This resulted in the symbolic link which exposes PowerShell to the Unix systems to be renamed. It was renamed to pwsh-preview for both macOS and Linux. We are considering something similar for Windows.

@markekraus

Not really! I went straight to the instruction docs and then did the deb package installation.

I will check the release notes! Hehe
:)

@MaximoTrinidad The instruction docs are for GA release versions. Preview and RC's live and die by the release notes. 😃

Ah! Got it now!

Well, a little bit of pain won't hurt. I'm guessing that's why the deb package is available. But, I'm surprise the path to pwsh is not set.

Thanks for clarifying!
:)
