Question

linux

Hello!
There was a following task.
There are two servers serv1 and serv2. There is a FileOne file on serv1. We need to add the content of this file to the FileTwo file on serv2, without losing the current content of FileTwo.
Can you please tell me which team can do this?

Answer 1

something like this
cat FileOne | ssh [user]@[server] 'tee -a /path/FileTwo'
