How can I use ssh to send the output of a program to another computer continuously over time until connection is closed?

Question

My first naive way would be writing the output (python script) into a file and send it via scp but given that there output is generated overtime (like inconstantly between 1s and 1 day periods) I don't think that opening a file, writing it and then sending it is the smartest way.

Is there a better way? It doesn't have to be ssh but something that does not require port-forwarding or UDP holepunching.

Does myprogram | ssh -o ServerAliveInterval=300 me@remotecomputer "cat > file" do what you want? — Mark Plotnick, Jan 05 '21 at 15:22
what i would to given that it can take a long time was to write the output to a file and then use SSHFS to mount it on the local machine and monitor the content. — BANJOSA, Jan 05 '21 at 16:27

Pipes

This is not an ssh problem. Read up on shell pipe-lines. How standard-out can be piped to a 2nd processes standard-in. see https://www.youtube.com/watch?v=bKzonnwoR2I for an introduction.

If you already know this then.

Consider ssh remote-machine remote-command to be equivalent to local-command. e.g. ssh remote-machine ls gets a directory list on the remote. ls | less puts a directory listing through a pager. So ssh remote-machine ls | less will put a remote directory list through a pager.
