Support for CHMOD to OpenSSH via Script

Hello community.
Our production FTP client is Ipswitch WS_FTP Pro. We have an implementation with a 3rd party that uses OpenSSH on a *nix server. We employ SCP scripts to do our work. We can upload files and delete files but found that we could not set permissions. Ipswitch support confirmed that while the GUI supports updating file permissions, the scripting utility does not.

Does WinSCP support a scripted CHMOD command with OpenSSH?

Yes, see:

You can actually even set permissions, when uploading already, using the -permissions switch of the put command:

Thank you for the reply.
It did work for us quite nicely.
