## Command `tmux-setup`

In the purpose of always making debugging sessions easier while being more effective, `GEF`
integrates two commands:

*  `tmux-setup`
*  `screen-setup`

Those commands will check whether GDB is being spawn from inside a `tmux` (resp. `screen`) session,
and if so, will split the pane vertically, and configure the context to be redirected to the new
pane, looking something like:

![gef-tmux-setup](https://raw.githubusercontent.com/hugsy/gef/refs/heads/main/docs/assets/images/gef-tmux-setup.png)

To set it up, simply enter

```text
gef➤ tmux-setup
```

**Note**: Although `screen-setup` provides a similar setup, the structure of `screen` does not allow
a very clean way to do this. Therefore, if possible, it would be recommended to use the `tmux-setup`
command instead.

### Possible color issues with tmux

On Linux tmux only supports 8 colors with some terminal capabilities (`$TERM` environment variable).
This can mess up your color themes when using GEF with tmux. To remedy this if your terminal
supports more colors you can either set the variable to something like `TERM=screen-256color` or if
you don't want or can't change that variable you can start `tmux` with the `-2` flag to force tmux
to use 256 colors.
