All,



I'm pull my hair out trying to work out the easiest way to retrieve a list
of file names without its extension. There seems to be no propriety on type
System.IO.FileInfo which does this. Can any body help me pls?

I'm sure its simple.

regards

gci | % { [IO.Path]::GetFileNameWithoutExtension($_) }

Jouko,

thats fantastic, however in the interests of fully understanding your answer
(which works perfectly). What is the significance of the %?

and the :: ? (does this call a static method?)

Many thanks again.

One possibility is extending the FileInfo type with a Basename property;
Jeffrey Snover discussed this in the developer blog at one point:
http://blogs.msdn.com/powershell/arc...24/645981.aspx


The latest form of the BaseName ScriptProperty, with corrections by Jacques
Barathon, is this:

if ( ($this.extension.length -gt 0)
-and ($this.extension.length -lt $this.Name.length) )
{
$this.Name.Remove($this.Name.Length - $this.Extension.Length)
}
else
{
$this.Name
}


You can also create a filter that will take FileInfo objects as input and
emit base names:

filter To-BaseName
{
if ( ($_.Extension.length -gt 0) -and
($_.Extension.length -lt $_.Name.length)
{ $_.Name.Remove($_.Name.Length - $_.Extension.Length)}
else
{ $_.Name}

}

If you use

RTFM

% = FOREACH-OBJECT

Still trying to understand the :: part thou

cheers

:: is used to access a static member. You can use Get-Member's Static
parameter to examine static members:

[IO.Path] | Get-Member -Static

Try this trick:
Use your favorite Search engine and search for:
PSMDTAG: FileInfo

PSMDTAG stands for PowerShell MetaData TAG

Actually, Jouko's static [IO.Path]::GetFileNameWithoutExtension() applied to
Jeffrey's extension to the FileInfo type looks best:

<Type>
<Name>System.IO.FileInfo</Name>
<Members>
<ScriptProperty>
<Name>Basename</Name>
<GetScriptBlock>
[IO.Path]::GetFileNameWithoutExtension($this)
</GetScriptBlock>
</ScriptProperty>
</Members>
</Type>

It allows you to do things like:
dir | ft basename,extension

If you are now wearing a big flashing question mark, read the PowerShell's
team blog to know what to do with the above lines :-)

If what you just did was subclass FileInfo, that's pretty cool. Strange that
you can do that considering FileInfo is sealed though... It's a twisted
world we live in where we have the object oriented world colliding with the
world of scripting. ;-)

Shhh. It's not subclassing. We just epoxied it onto the trunk.
