I'm happy to report that Royal TSX 4.0 has been released and includes support for specifying an SFTP custom command.
For more information about the major new features of Royal TSX 4.0, please head over to our major upgrade landing page.
I would like to see the support of a SUDO command for the file transfer plugin. So that I can use a "userA" to connect to the server but then make "sudo su - userB" to switch to another user (e.g. "root").
Many environments do not allow the connection with "root" but only with a non-privileged user. If you then need to to transfer files as "root" you cannot do that.
I also have environments where I need to switch to another user (not "root") after login. So I would like to see a configurable option which sudo command is used, just as we have it on Windows with WinSCP today.
