How to send data to local clipboard from a remote SSH session

My favorite way is ssh [remote-machine] "cat log.txt" | xclip -selection c. This is most useful when you don’t want to (or can’t) ssh from remote to local.

Edit: on Cygwin ssh [remote-machine] "cat log.txt" > /dev/clipboard.

Edit: A helpful comment from nbren12:

It is almost always possible to setup a reverse ssh connection using SSH port forwarding. Just add RemoteForward 127.0.0.1:2222 127.0.0.1:22 to the server’s entry in your local .ssh/config, and then execute ssh -p 2222 127.0.0.1 on the remote machine, which will then redirect the connection to the local machine. – nbren12
