Dropdown terminal is a very useful utility that shows a command line terminal in a dropdown popup on the screen just by pressing a button like F12.
These provide easy access to the command line and enhance productivity on Linux Desktop.
There are multiple packages available for Ubuntu and similar distros, that provide a dropdown terminal.
These include Yakuake (for KDE), Guake (for Gnome) and Tilda (for Xfce).
Lets check them one by one.
1. Yakuake
Yakuake is a dropdown terminal for KDE desktop. Pressing the F12 button will bring up the terminal.
Here is a screenshot of Yakuake running on Kubuntu 20.04
Install with the apt-get command
$ sudo apt-get install yakuake
After installation it can be launched from the shortcut in K > System > Yakuake. To add new Session press Ctrl+Shift+N
To autostart yakuake on system boot add it to the list of statup programs in
System Settings > System Administration > Startup and Shutdown > Autostart
2. Guake
Guake (Quake style terminal) is a dropdown terminal application for the gnome desktop.
Here is a screenshot of Guake running on Ubuntu 20.04
Install Guake with the apt-get command.
$ sudo apt-get install guake
Guake also uses the F12 key by default for launching the terminal, and this can be changed in the Guake Preferences program.
3. Tilda
Tilda has a simpler look and is suitable for a desktop environment like Xfce.
Install with the apt-get command
$ sudo apt-get install tilda
Conclusion
The dropdown terminals show at the press of a key and then hide back when you are working with some other application. That way they can continue doing a background task.
Further more you can have multiple tabs inside the terminals get as many shell prompts as needed for your tasks.
