SFTP from one remote server to another remote server from desktop

Hi,

I have 1. lappy
2. server A
3. server B

Now, what i need is to run a command from lappy that will sftp a file from server A to server B.

Please guide me to achieve this.

look up scp usage for your system. i.e., man scp

You have to ssh enabled, and private ssh keys set up as well.
