Tutorial to learn the steps involve in how to install the Terminator Terminal emulator app on Ubuntu 22.04 LTS Jammy Jellyfish Linux.
Terminator is an open-source terminal multiplexer written in Python that allows you to use multiple terminals within a single window and switch between them using keyboard shortcuts. This is similar to the tiling mode of window managers. So you can keep several shells open at the same time without tabs or other terminal windows.
Originally developed for GNOME, the program can now be used with any desktop environment. In contrast to programs such as Screen or tmux, however, an XServer (graphical desktop) is explicitly required.
If you are looking for a great Terminal emulator for the GNOME desktop environment, the Terminator Terminal emulator is the best one for you. Among other features of the Terminator emulator, Terminator solves the problem associated with opening multiple tabs in a single Terminal window. You can seamlessly arrange the Terminal tabs with Terminator.
Terminator basically comes with a lot of customization options, which can help you arrange the Terminals in a grid-shaped arrangement, besides support for multiple tabs. With the number of key bindings, you can carry out the most common activities, and you can easily drag and drop tabs for the purpose of ordering them and enjoy a streamlined workflow. Terminator has support typing the same text in multiple Terminal instances at the same time, which can also be useful in certain situations.
