How to get the results of LS into a variable

2024-09-09 21:38

I want to automate the following:

Open my defined site
Run ls—which is a supported command—and have the output from it go to a variable, a file, *anything* that I can then read back into the next step of my PowerShell script.

Automation works fine. I can open my defined site, create directories, upload and download files. I'm guessing ls is working just fine, but there's no obvious way to capture the output.

How can I accomplish this?

In PowerShell, do not use scripting. Use WinSCP .NET assembly:

Then you can use Session.ListDirectory to retrieve contents of a remote directory to a variable.

Martin, thanks. I'm not having success that way. I get this error:

 New-Object : The member "Site" was not found for the specified .NET object.
At line:5 char:23
+     $sessionOptions = New-Object WinSCP.SessionOptions -Property @{
+                       ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [New-Object], InvalidOperationException
    + FullyQualifiedErrorId : InvalidOperationException,Microsoft.PowerShell.Commands.NewObjectCommand
 
Error: Exception calling "Open" with "1" argument(s): "Value cannot be null.
Parameter name: sessionOptions"

I'm guessing it doesn't like this:

$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Site = "MySiteName"
}

I have my site defined in the GUI. How do I invoke it as a property of SessionOptions?

There's indeed no Site parameter.
WinSCP .NET assembly in general does not use GUI configuration. It's completely isolated.
You have to configure the session in the script using SessionOptions properties.
