Removing path and extension from filename in PowerShell

Question

There's a handy .NET method for that:

C:\PS> [io.path]::GetFileNameWithoutExtension("c:\temp\myfile.txt")
myfile

Way easier than I thought to address the issue of displaying the full path, directory, file name or file extension.

$PSCommandPath
(Get-Item $PSCommandPath ).Extension
(Get-Item $PSCommandPath ).Basename
(Get-Item $PSCommandPath ).Name
(Get-Item $PSCommandPath ).DirectoryName
(Get-Item $PSCommandPath ).FullName
$ConfigINI = (Get-Item $PSCommandPath ).DirectoryName+"\"+(Get-Item $PSCommandPath ).BaseName+".ini"
$ConfigINI

other forms:

$scriptPath = split-path -parent $MyInvocation.MyCommand.Definition
split-path -parent $PSCommandPath
Split-Path $script:MyInvocation.MyCommand.Path
split-path -parent $MyInvocation.MyCommand.Definition
[io.path]::GetFileNameWithoutExtension($MyInvocation.MyCommand.Name)

Inspired by an answer of @walid2mi:

(Get-Item 'c:\temp\myfile.txt').Basename

Please note: this only works if the given file really exists.

or

([io.fileinfo]"c:\temp\myfile.txt").basename

or

"c:\temp\myfile.txt".split('\.')[-2]

you can use basename property

PS II> ls *.ps1 | select basename
