Issue Description

I'm seeing some bugs when I try to use the PowerShell: Expand Alias VSCode command. The first time I tried to use it, I received an exception saying the "sequence contains no elements," but now that I've restarted the PowerShell session, it's just prompting over and over, without actually doing anything.

All I've typed is: gps followed by ALT / OPTION + SHIFT + E to invoke Expand Alias.

Attached Logs

Follow the instructions in the README
about capturing and sending logs.

Interesting. I see one more prompt string appear after exansion (with no linebreak like you're seeing).

[daviwil]

I think it shows multiple times in his screenshot because he's run Expand Aliases a bunch of times. Looks like the way we're running that command in the session isn't properly causing a newline to be written. Also, I'm betting that the expansion is actually happening but there's just nothing in the file to expand. If you use gci in the file, does it get expanded?

[rkeithhill]

I should have mentioned that all the aliases I tested were expanded but then again, I'm testing on Windows / Windows PowerShell.

@daviwil @rkeithhill That's the weird thing, expansion isn't actually occurring for me. I tried both gci and gps. Will send logs over.

Thanks a lot!

This line is getting printed repeatedly in the EditorServices.log file. Also e-mailed you the full log.

The term 'Sort' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

[daviwil]

Thanks Trevor! I think the alias for Sort-Object may not be available on Linux/macOS, just need to update the logic for the alias expansion command.

Closing as this should be resolved
