PowerShell 6.0 - Linux

[patrolez]

Hi, I am trying PowerShell in Linux and maybe as you know PowerShell 6.0 is developed to be able to work with .NET Core "stack".

I have made some changes to get z working with Linux as there are some platform related differences, but that changes are made in "hacking" manner. It would break Windows platform.

I have seen that some of regular expressions are build during runtime based on "Get-PSProvider" output.

In Linux the output looks like:

Get-PSProvider

Name          Capabilities                          Drives     
----          ------------                          ------     
Alias         ShouldProcess                         {Alias}    
Environment   ShouldProcess                         {Env}      
FileSystem    Filter, ShouldProcess, Credentials    {/}        
Function      ShouldProcess                         {Function} 
Variable      ShouldProcess                         {Variable}

Diff is pretty simple. In Linux there is different convention in FileSystem tree traversal. Things are not accessed via <DRIVE/RESOURCE>:\.

 }

For now I have no knowledge to provide some changes to not break Windows platform, so this is in some way Feature Request :D

Thank you for taking the time to submit this request.

Although I use Linux from time to time, it's not enough to justify the hours it would take to get it working and tested. If I had unit tests written in Pester I think I'd probably have the confidence to do this :-)

If you would like to do the changes to make it compatible I'd be more than happy to have the branch installed on my Windows machine for testing purposes. If the branch proves stable after some use, then I'm happy for it to go into master.

I totally forgot to mention that this PowerShell script is a port of a bash script. See https://github.com/rupa/z
