It's answered above already.
Also, nowadays, WinSCP GUI can generate a script template for you:

How can we connect using private key

I have decided to usе a saved session.
Thank you!

There should be a dash, not slash before privatekey, i.e. -privatekey=
See https://winscp.net/eng/docs/scriptcommand_open

1. the simple commands winscp.com /command "open user@sftp_srv" /privatekey=c:\private.ppk or winscp.exe /console.... work perfectly.

2. But I want to use a script file

winscp.com /script=script_file.txt and in the script_file.txt I specify the private key

open user@sftp_srv /privatekey=..... This does not work and the error is "Too many parameters with open". Apparently the /privatekey switch here is the problem because without it, the script starts to open the session - of course it fails.
Is there a way to use /privatekey within a script file ?

Thanks

Thanks, I will try it.
Yes, cli is command line interface!

What do you mean by CLI? Scripting?
Use -privatekey= switch of open command:
https://winscp.net/eng/docs/scriptcommand_open

If you really mean command-line, there's equivalent /privatekey= command-line parameter:
https://winscp.net/eng/docs/commandline#session

Here it is the picture, so the things are clearer :)

How to specify the private key with CLI, this is not the Host key, right ?

Hi,

I need to connect to a SFTP server with a private .ppk key. I can connect with no problems with WinSCP GUI.
I am trying with CLI, but now luck. Could you, please, tell me the exact syntax of the command I must use.

Thanks
