WinSCP script: Unknown command 'ssh-rsa'

Question

I have WinSCP script connecting to am SFTP site. It establishes connection and says "starting session" but exits.

This is my script FilePull.txt:

open sftp://***:****@sftp.****.com:22  -hostkey="
ssh-rsa 1024 **********"

which is being called as:

Winscp.exe /console /script="C:\FilePull.txt" /log="C:\winscp.log" /loglevel=0

This is from winscp.log:

It should connect to SFTP site and get the files.

If you really have the open command in two lines, then the problem is obvious.

It should be

open sftp://***:****@sftp.****.com:22  -hostkey="-rsa 1024 **********"

instead of:

open sftp://***:****@sftp.****.com:22  -hostkey="
ssh-rsa 1024 **********"

Additionally, there's nothing in your script, what would make WinSCP "get the files".
