TODO tutorial / guide for tmux
==============================


## [ ] Terminologies

* "session" : the entire session
* "screen" : a separate shell / CLI / TUI program spawned by tmux and whose display is accesible from tmux.

## [ ] Cheatsheet

See its own cheatsheet draft.


## [ ] Using tmux to have persistent terminal on HPC

### Draft:

The tmux process should be run on the login node instead of the compute node.
Spawn as many screens as from one or more screen(s) / shell(s) within the tmux session.
For heavier process, we should launch the "salloc" to get the shell on the compute node before running the heavy process.
