This is why I pay attention to things like shell and GNU tools, because knowing them well is often more than a half of job done. Afterwards, I found out that having just one terminal window is not enough. Even though having many windows represented by tabs in Linux terminal-handling tools or by many Putty instances can solve this problem, it is often desired to keep things in sight at the same time. For example, we may want to execute some code or tests and at the same time watch over log files by using tail. Terminator seemed to me the right tool to do the job.

There are many ways to automate tasks across systems. Ansible , for instance, ensures all systems are in the same state, and sometimes a simple cron job will do. But sometimes you need to run commands manually. For that, you need tmux , a single terminal that puts you in control of multiple command prompts. The result is a tabbed interface without the physical tabs , so you can flip from one open terminal to another without having to use the mouse the way you have to when switching from one tab in Firefox to another.

However, tmux adds in the ability to split a window into panes, with each pane containing a separate terminal, and each terminal can be logged into a separate host. You can build an array of terminals with just a few keyboard shortcuts or a rudimentary tmuxinator script.
