Uxterm. How to make export work between 2 tabs?

Question

bash

I want to fasten ssh-agent. I use eval `ssh-agent -s`.
The problem is that it exportdoesn't work the way I would like it to.
If in the same tab after eval `ssh-agent -s`register set | grep SSH_, then the set variables are displayed.
I open a new window - there are no variables.
What to do?

Answer 1

if in a simple way - no way: export works within the current shell (and its descendants), and different tabs = different / independent shells.
as an option - write these variables to a file, which should be included in the profile/rc-file.
