The printable version is no longer supported and may have rendering errors. Please update your browser bookmarks and please use the default browser print function instead.

Guake is a top-down terminal for GNOME (in the style of Yakuake for KDE, Tilda or the terminal used in Quake).

Installation

Install the guake package.

Usage

Once installed, you can start Guake from the terminal with:

$ guake

After guake has started you can right click on the interface and select Preferences to change the hotkey to drop the terminal automatically, by default it is set to F12.

Autostartup

You may want Guake to load on starting up Desktop Environment. To do this, you need to

# cp /usr/share/applications/guake.desktop /etc/xdg/autostart/

See Autostarting for more info.

Guake scripting

Like Yakuake, Guake allows to control itself at runtime by sending the D-Bus messages. Thus it can be used to start Guake in a user defined session. You can create tabs, assign names for them and also ask to run any specific command in any opened tab or just to show/hide Guake window, manually in a terminal or by creating a custom script for it.

Example of such a script is given below this section.

You can use guake executable itself to send D-Bus messages. Here is the list of available options you may be interested in:

-t, --toggle-visibility — toggle the visibility of the terminal window. Actually, you can just type guake, and it will toggle the visibility of already running instance.
-f, --fullscreen — put Guake to fullscreen mode.
--show — show Guake main window.
--hide — hide Guake main window.
-n CUR_DIR, --new-tab=CUR_DIR — create new tab and select it. Value of CUR_DIR used to set a current directory for the tab, if specified.
-s INDEX, --select-tab=INDEX — select tab with index INDEX. Tab indexes are started with 0.
-g, --selected-tab — print index of currently selected tab.
-e CMD, --execute-command=CMD — execute an arbitrary command CMD in the selected tab.
-i INDEX, --tab-index=INDEX — used with --rename-tab to specify index INDEX of a tab to rename. Default value is 0.
--rename-tab=TITLE — set the tab name to TITLE. You can reset tab title to default value by passing a single dash ("-"). Use -i option to specify which tab to rename.
--bgcolor=RGB — set the hexadecimal (#rrggbb) background color RGB of the selected tab.
--fgcolor=RGB — set the hexadecimal (#rrggbb) foreground color RGB of the selected tab.
-r TITLE, --rename-current-tab=TITLE — same as --rename-tab, but renames the currently selected tab.
-q, --quit — shutdown running Guake instance.

Multiple options may be combined in a single call. If there is no guake instance running, all of the options specified will be applied to the newly created instance.

To display list of all available options, type guake --help.

There are 2 ways of starting guake while applying these scripts

copying the below example into a file like guake-init.sh making it executable and running that file instead of guake
right clicking on Guake Terminal > Preferences > Hooks and adding the path to the guake-init.sh script in the "On start:" field while making certain to comment out /usr/bin/guake & and sleep 5 from the script below

The second option is preferable if you want the script to run regardless of how guake is started and you can still instruct guake not to run the script with guake --no-startup-script if needed.

Example:

#!/bin/bash

/usr/bin/guake &
sleep 5 # let main guake process start and initialize D-Bus session

# adjust tab which was opened by default
guake --rename-tab="iotop" --execute="/usr/bin/iotop"

# create new tab, start bash session in it
guake --new-tab --execute="/usr/bin/bash"
# and then execute htop, renaming the tab to "htop"
guake --execute="/usr/bin/htop" --rename-current-tab="htop"

# ...
guake --new-tab --execute="/usr/bin/bash"
guake --execute="/usr/bin/atop" --rename-current-tab="atop"

guake --new-tab --execute="/usr/bin/bash"
guake --execute="~/.iptables.sh" --rename-current-tab="iptables -nvL"

guake --new-tab --execute="/usr/bin/bash"
guake --execute="/usr/bin/journalctl --follow --full" --rename-current-tab="journalctl"

guake --new-tab --execute="/usr/bin/bash"
guake --execute="/usr/bin/irssi" --rename-current-tab="irssi"

guake --new-tab --execute="/usr/bin/bash"
guake --execute="/usr/bin/sudo -i" --rename-current-tab="rootshell0"

guake --new-tab --execute="/usr/bin/bash"
guake --execute="/usr/bin/sudo -i" --rename-current-tab="rootshell1"

guake --new-tab --execute="/usr/bin/bash"
guake --rename-current-tab="shell0"

guake --new-tab --execute="/usr/bin/bash"
guake --rename-current-tab="shell1"

Notice than we should wait some time calling sleep to avoid race conditions between running instances.

Warning: --execute option can make harmful things on a tab running text interface program, like fdisk or innotop. Use it with caution. There is a bug on github about it: guake#921.

Troubleshooting

Floating mode in window managers

Guake may not open in floating mode with some window managers. This can be resolved by using Guake's window class string ("guake" or "Guake" per xprop WM_CLASS). For example, see "WM_CLASS" in i3#Correct handling of floating dialogs for i3.

Toggling Guake visibility does not work (Wayland)

If you are using Wayland, the Guake visibility toggle hotkey may not work under some applications. This is because Guake uses a global hotkey library made for X environments and there is no equivalent global hotkey interface for Wayland. Many applications (e.g. Firefox) run on Wayland through XWayland where the Guake toggle will work but others that natively run Wayland (e.g. GNOME apps) disable Guake toggle functionality.

If you do not wish to switch over to an X environment, a simple workaround requires configuring a shortcut with your window manager/desktop environment for the command guake-toggle.

See github issue for more details.

Note: Using guake-toggle is recommended over guake -t. It is much faster since it goes directly over D-Bus without fully initializing Guake.
