Cockpit is a HTML5 app to create panes and windows in Tmux. Configure your workspace, download the script and run it :)
To run the downloaded file, you need to give necessary permission. At the Unix / Linux prompt, you should enter $ chmod +x filename.sh, and run it by entering $ ./filename.sh
** Make sure you have ‘tmux’ pre-installed in your system.
Gracias, muy apreciado
