How to send a output of unix command from one server to another server?

Question

How to redirect the output of a unix command from one server to another server.

I should be able to send the unix command's output from server-1. Then I should be able to receive the output in Server-2 and write it into a file.

General, you can always do:

<command> | ssh user@remote-server "cat > output.txt"

It saves output of <command> to output.txt file in remote server.

In your case, on Server-1:

echo "qwerty" | ssh user@Server-2 "cat > output.txt"

If two servers have no connectivity, but you can ssh to both servers, then from local machine, you can do:

ssh user@Server-1 "<command>" | ssh user@Server-2 "cat > output.txt"

You can run:

ssh remote_server "command" > file_on_local_host.txt

or use the output as an input for local command:

ssh remote_server "remote_command" | local_command

Since you can't connect directly from server 1 to server 2 you can use this, having your local machine in the middle:

ssh server1 command | ssh server2 "cat > output.txt"
