Call Set-Location from within a cmdlet

Question

I'm creating a cmdlet for PowerShell and I need to be able to call Set-Location (aka cd) from within a the cmdlet. I would do it like this

var setLocation = new Microsoft.PowerShell.Commands.SetLocationCommand();
setLocation.Path = path;
setLocation.Invoke();

except that it gives me an error that says You cannot invoke a cmdlet that derrives from PSCmdlet. I'd like to use Set-Location, but I'd be happy with just simply changing the directory of the shell.

Answer 1

The best answer I could find was to use InvokeScript to change directory:

InvokeCommand.InvokeScript(string.Format("Set-Location {0}", fullPath));

It's possible that there's a "more C#" way to do this, but I couldn't find it.

Answer 2

The question is a bit older but here is a slightly nicer solution:

The class PathIntrinsics contains the method SetLocation.

To manipulate the path of the current session, you can access the PathIntrinsics via the SessionState using the Path property.

long story short:

SessionState.Path.SetLocation("C:/some/path");

Answer 3

You could try to derive from CMDLET not PSCMDLET.

Answer 4

Simply using Set-Location inside the script should do the work.

So for example:

# Script.ps1
CD ~
Get-Location
Set-Location c:\Windows
Get-location

Once the script finishes, try Get-Location again!

Answer 5

If I use Set-Location in a script, I usually like to first use Push-Location to store the current location and then at the end of my script I can use Pop-Location to return the user to where they were.

Push-Location $PWD
Set-Location $somewhere
#script body
Pop-Location

Unless of course, the intention of the script is to change directories for the user.
