Vista - PSDrive Function

I am trying to set up a function that allows me type in "Script:" <no
quotes> and go to a PSdrive I have mapped on the local file system, just
like typing C: or D: would. I wrote this function for my profile:

function global:Script: { Set-Location Script: }

I modeled after the function in profile.ps1 file in the example directory.
Seems pretty simple, I do a dir on the Function drive and it shows up as
Script: and looks fine, but if I type Script: I get a function does not
exist error. However, if I run type global:Script: it works fine.

Any help would be great,

Your problem comes down to the use of Script: I think. PowerShell has a
number of levels of scope for variables including global, local and script.
See

get-help about_scope for full details

When you just type script: Powershell's assumption is that you are dealing
with the script scope and it can't find the function. When you type
global:script: you are explicitly telling PowerShell to use the script:
function in the global scope which it does know how to find.

If you use a different name instead of script it should work. I tested your
function as

function global:Scripts: { Set-Location Script: }

and it worked - with or without the use of global:

Hope this helps

In my case, I keep my scripts in d:\foo. I use:

PSH [D:\foo]: New-PSDrive -name script -psProvider filesystem -root
d:\foo

Name Provider Root
---- -------- ----
script FileSystem D:\foo

PSH [D:\foo]: dir script:

Directory: Microsoft.PowerShell.Core\FileSystem::\foo

Mode LastWriteTime Length Name
---- ------------- ------ ----
....



Hope this helps.

Brian,

I think that PowerShell is treating "script" in some respects as if it
was a reserved word.
