How to concat path and file name for creation and removal

问题

I'm trying the following.

$woohoo = "c:\temp\shabang"
New-Item -ItemType File $woohoo

This creates a file at desired location. However, I'd like to split the $woo and $hoo and go something like this.

$woo = "c:\temp"
$hoo = "shabang"
New-Item -ItemType File ($woo + $hoo)

This doesn't work and I need a hint on how to make it fly. This suggestion nor this on worked out when applied to my situation. Apparently - given path format is unsupported.

Suggestions?

Edit

This is what it looks like:

Edit 2

$woo = "c:\temp"; $hoo= "shabang"; New-Item -ItemType File (Join-Path $woo $hoo)

回答1:

Doing $woo + $hoo does not return the proper filepath:

PS > $woo = "c:\temp"
PS > $hoo = "shabang"
PS > $woo + $hoo
c:\tempshabang

Instead, you should use the Join-Path cmdlet to concatenate $woo and $hoo:

New-Item -ItemType File (Join-Path $woo $hoo)

See a demonstration below:

PS > $woo = "c:\temp"
PS > $hoo = "shabang"
PS > Join-Path $woo $hoo
c:\temp\shabang
