How to execute an ssh session defined by a string, in the same shell?

Problem:

I've got a script that generates an ssh command string to generate an ssh session to a remote shell. I want to run this like the following:

function_name args | bash

However it executes the ssh command in a subshell (apologies if that's the wrong terminology) and I can't then use it.

What's the correct way to run this so it executes in the same shell, and I can then write into that shell?

Aside:

For those who wanted the function, it's:

function shortcut_for_ssh(){
   grep ssh notesfile | grep $1
}

Yields

ssh user@hostname
Solution

  • Source it.

    . <( function_name args )

    That or an exec or something like it.

    I will assume you trust the function ...
