I want to copy content from file on one linux server to file on another linux server with ssh. I am on third machine and I am using one same public key on both linux servers to connect without password.

I know that is something like this:

ssh -A user1@server1 "cat fajl1..."

Use the ssh in a pipe. I will assume you have machines server1, server2 and server3. If you are on server 2, it would look like this:

ssh -A user1@server1 "cat server1file" | ssh user1@server3 "cat >> server3file"

The first ssh command starts a pipeline over the network that the second ssh command picks up and appends to the destination file on its file system.

  • My example was too simple and did not address your 3 machine problem. I have adjusted the answer.

  • Works! That is right command, I put pipe under " " each time and that messed up everything.Thanks!
