How to normalize a path in PowerShell?

Question

I have two paths:

fredfrog

and

..frag

I can join them together in PowerShell like this:

join-path 'fredfrog' '..frag'

That gives me this:

fredfrog..frag

But I don't want that. I want a normalized path without the double dots, like this:

fredfrag

How can I get that?

Answer 1

You can expand ..frag to its full path with resolve-path:

PS > resolve-path ..frag 

Try to normalize the path using the combine() method:

[io.path]::Combine("fredfrog",(resolve-path ..frag).path)
