Greetings,

 

I've authored a plugin to install Microsoft PowerShell. The plugin is found here: https://github.com/x-radeon/unraid-powershell

 

Please note I'm not experienced with writing plugins for Unraid, so install at your own risk. I use the plugin on two of my Unraid installs to manage my BTRFS snapshots with no issues, so I know it works. If you know how to write plugins, please help improve it!

 

Steps to install:

 

1. On your Unraid install go to Plugins > Install Plugin
2. For the URL, paste in https://raw.githubusercontent.com/x-radeon/unraid-powershell/main/PowerShell.plg
3. Click Install

 

To use PowerShell after install, type pwsh at a terminal or call pwsh in a bash script (when using 'User Scripts" for example) like so:

#!/bin/bash

pwsh /boot/config/plugins/myscripts/script.ps1

 

-xRadeon

Is it possible to have a Docker container access pwsh.exe ?, I've installed the plugin but I can't find the directory in the file system where pwsh.exe is

Edited November 16, 20232 yr by Mephisto76

When installing the plugin untars the files to this directory "/opt/microsoft/powershell/7/". The pwsh binary file is inside that directory and it's not an "exe" file, it's a native Linux binary file that's named just 'pwsh'.

 

As for docker, I guess what you could do is map "/opt/microsoft/powershell/7/" to some path in the container and then you should be able to call pwsh from that path. I don't know if it would work. Some dockers are very cut down so I'm not sure if pwsh will have access to everything it needs to run properly, but I'm not an expert or anything so maybe it will work just fine, idk.

 

Good luck!

Does this stay after reboot?

Yes, it will re-install after a reboot by using the already downloaded gz file.

What about any of the modules installed (for example AZ). Are they also retained post reboot?

No, most likely not. It's installed into the ram drive, so on a reboot it has to be re-installed. Could potentially use the User Scripts plugin to auto install your module(s) on a reboot.

alright, thanks for clarifying.

Was curios if this plugin was also compatible/would work with 7.0/7.0.1
Looking for a new way to add PowerShell without Nerdtools. Thanks! 

Yeah, it works just fine on version 7. 👍

Still works flawlessly. (A late) thanks for this Plugin. Had stability issues with powershell in docker containers, didn't know there was a plugin until today :)

Yep, it's still kicking. I use it every day to do my BTRFS snapshots. 👍

Anybody else having problems with powershell after updating to 7.2.0?

Script don't work anymore, command pwsh doesn't give me a prompt, just prints the version (7.5.3) and then nothing..

I haven't upgraded just yet to 7.2.0. I'll try to get upgraded in the next day or two and see what's going on.

Thank you. I am not sure if it is really the update causing this or something else. But the timing makes it hard to ignore suspicious.

@xRadeon Any news, findings?

fyi: with an update to 7.2.2 the problem has been fixed. I'm not sure if the problems was related to 7.2.0 or something on my machine caused it.. Just happy my script work again :)

Oh sorry man, I got super busy during the holidays and just never got around to this.

I did upgrade and powershell was still working fine for me. I think I've done another upgrade since then and it's been working.

Not sure what it was, perhaps a uninstall/reinstall of plugin could have resolved it.
