"Cannot bind argument to parameter 'FilePath' because it is null" on Ubuntu

Hello, I'm using:

$PSVersionTable          

Name                           Value
----                           -----
PSVersion                      6.2.4
PSEdition                      Core
GitCommitId                    6.2.4
OS                             Linux 4.15.0-76-generic #86~16.04.1-Ubuntu SMP Mon Jan 20 11:02:50 UTC 2020
Platform                       Unix
PSCompatibleVersions           {1.0, 2.0, 3.0, 4.0…}
PSRemotingProtocolVersion      2.3
SerializationVersion           1.1.0.1
WSManStackVersion              3.0

I've just ran an Install-Module z -AllowClobber -Scope CurrentUser and tried this plugin for the first time. As soon as a 'cd' to another directory I get an error in my terminal saying:

System.Management.Automation.ParameterBindingValidationException: Cannot bind argument to parameter 'FilePath' because it is null.
   at System.Management.Automation.ExceptionHandlingOps.CheckActionPreference(FunctionContext funcContext, Exception exception)
   at System.Management.Automation.Interpreter.ActionCallInstruction`2.Run(InterpretedFrame frame)
   at System.Management.Automation.Interpreter.EnterTryCatchFinallyInstruction.Run(InterpretedFrame frame)
   at System.Management.Automation.Interpreter.EnterTryCatchFinallyInstruction.Run(InterpretedFrame frame)

I think this is down to using $ENV:USERPROFILE rather than the interop version of $ENV:HOME at this line: https://github.com/vincpa/z/blob/master/z.psm1#L1

That made the error go away locally for me, but the plugin still didn't seem to work right. Is there any interest in making this plugin work on platforms other than Windows? I'd be happy to make it work if a PR would be accepted?

Thank you, Joe.
