Use the GetFileName Method to Extract the Filename From a Path in PowerShell. The GetFileName method of the . NET's Path class returns the file name and extension of the specified path.
Change file extensions with PowerShell You can also use the Rename-Item to change file extensions. If you want to change the extensions of multiple files at once, use the Rename-Item cmdlet with the Get-ChildItem cmdlet.
Use the Get-ChildItem cmdlet to get the file item and using its Extension property it returns the file name extension. The Get-ChildItem command accepts the file path as input and gets the file item. It then passes the output to the Select command to get file extension using the Extension property.
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
