Resolve-Path whilst in a PSDrive doesnt return the full (non-relative to PSDrive) path

[kilasuit]

When in a script or interactive use and you have defined a PSDrive as a shortlink to another location on the same disk Resolve-Path returns the PSDrive relative file path whereas I think that it should be able to return the actual full file path instead similarly to how Get-Item returns the non-relative PSDrive path and shows this correctly under the PSPath & Fullname properties

Steps to reproduce

Create new PSDrive to C:\temp folder - New-PSDrive -Name CT -Root C:\temp -Provider FileSystem
Create file test.txt in C:\temp folder - New-Item C:\temp\test.txt
cd to the PSDrive -Set-location CT:\
Run Resolve-Path test.txt

Expected behavior

Resolve-Path returns the full path to the file so output should be C:\temp\test.txt

Actual behavior

Resolve-Path returns the PSDrive relative path so it returns CT:\test.txt

Unless we add a new, opt-in parameter, this is a breaking change that would require a (brief) Committee vote.

[mklement0]

I don't think a change is warranted:

Remember that Resolve-Path :

• makes no promises of returning a provider-native path - that's what Convert-Path is for.

• returns [System.Management.Automation.PathInfo] instances that also contain the provider-native path.

Thus, to get what you want - a provider-native absolute path string - all you need to do is:

> Convert-Path test.txt
C:\temp\test.txt

which is effectively the same as:

> (Resolve-Path test.txt).ProviderPath
C:\temp\test.txt

[joeyaiello]

@mklement0 yeah, I'm good with that. Convert-Path works just fine on all platforms.

Didn't think to use Convert-Path at the time - thanks @mklement0 for mentioning this and reminding me :-)
