Command for SSH with @ in User Name

I am trying to log into a server using SSH through the command line. I understand that the format is sftp -oPort=22 Username@Hostname. My issue is that my user name also has an @ symbol in it. Can someone tell me how I can get the system to not think that the last half of the user name as part of the hostname.

For example, my username is user@name. My hostname is hostname. When putting in the command, I am using sftp -oPort=22 user@name@hostname. The results I am getting is a request for the password for name@hostname.

Any help you can give would be greatly appreciated.

Did you give a try passing user@name in quote as 'user@quote'

would suggest you could either try escaping (sdfg\@fgh ) or quoting ('abcd@defg')

but since I'v never come across @ in a username before, out of interest, what OS are you on that allows "@" to be used as such?

Usernames are never supposed to contain @, from man useradd:
       Usernames must start with a lower case letter or an underscore,
       followed by lower case letters, digits, underscores, or dashes. They
       can end with a dollar sign. In regular expression terms:

Many things are written to this spec.

Thank you all for your suggestions. None of them worked. As to the OS question, I do not know the answer.

We found a way to make this work. Just in case anyone would like to know, now or in the future, I will detail what we did. We have tested this for Unix. I don't know how this will effect other systems.

In the .ssh folder on your server, create a file called config.
In that file, type the following:

Host <trading partner name i.e. bookstore>

HostName <actual hostname used for connection>
User <actual user name used for connection>
Port 22

Then, when you login from the command line, type sftp bookstore.
Press enter. The results will be a connection where it will tell ask you for the user@hostname's password.

That's a neat workaround. Have to remember that.
