How can I script the settings made by gnome-tweak-tool?
Solution 1
Easily find out what is being set
Instead of searching through a whole directory of options:
- Open a terminal window
-
Run the command:
dconf watch /
-
Make your changes and see what the terminal shows:
...and there you are.
Dconf & gsettings
In the example, you see the output from dconf
. Gsettings is the cli- frontend to dconf. Many times, you can use both a dconf
command or a gsettings
command. In this case either:
dconf write /org/gnome/desktop/background/show-desktop-icons false
or:
gsettings set org.gnome.desktop.background show-desktop-icons false
If the gsettings key exists however, the latter is considered to be better practice, to protect the integrity of your dconf
database.
Solution 2
For most of the settings you can use this approach:
-
Export the list of
gsettings
into a temporary file:gsettings list-recursively > /tmp/gsettings.before
Make your changes by
gnome-tweak-tool
(orunity-control-center
);-
Export the list of
gsettings
into an another temporary file:gsettings list-recursively > /tmp/gsettings.after
-
Compare the two files (.before and .after) and get the differences:
diff /tmp/gsettings.before /tmp/gsettings.after | grep '[>|<]'
Or compare and get only the new values (source):
diff /tmp/gsettings.before /tmp/gsettings.after | grep -Po '> \K.*'
Or compare and get only the new values, but replace the beginning of the lines with
gsettings set
to prepare a list of commands, that cold be stored directly within your script file (source):diff /tmp/gsettings.before /tmp/gsettings.after | sed 's/>/gsettings set/;tx;d;:x'
You can run all these commands from one line (or you can create a script to automate the process):
gsettings list-recursively > /tmp/gsettings.before; gnome-tweak-tool; gsettings list-recursively > /tmp/gsettings.after; diff /tmp/gsettings.before /tmp/gsettings.after | grep '[>|<]'
The next demo is created within Ubuntu 16.04. I think the approach shall work also within 17.10:
Update: I just found an easy way within Ubuntu 17.10:

I like to be able to configure things from the command line, so that when I reinstall the OS I can just run a script and get my preferred configuration back.
Since "upgrading" to Ubuntu 17.10, I found I had to use gnome-tweak-tool to get some settings the way I want them.
Once I find a setting in the gnome-tweak-tool GUI, how can I figure out its scriptable translation?
For example the following gsettings lines match the relevant entries in the gnome-tweak-tool screen shot below...
gsettings set org.gnome.desktop.wm.preferences titlebar-font "Tahoma Bold 8" gsettings set org.gnome.desktop.interface font-name "Tahoma 8" gsettings set org.gnome.desktop.interface document-font-name "Tahoma 8" gsettings set org.gnome.desktop.interface monospace-font-name "FixedSC 10"
...but how could anyone guess that? And how would I, for example, figure out where to get the corresponding settings for hinting and antialiasing?

Admin over 6 yearsTBH I've always resorted to grepping the keyspace e.g.
gsettings list-recursively | grep -e alias -e hint
- would love to know if there's a better way -
Admin over 6 yearsAside from browsing the source code or dconf-editor (or gsettings directly, like @steeldriver), not much anybody can do.

st01 over 6 yearsThis is brilliant, thank you. Small questions: (1) how do I know "if the gsettings key exists"? (2) What is the point of two command line interfaces that are for all intents and purposes identical to the user? (3) what's the difference between the first and the third of your "here"? They look like the same page to me.

st01 over 6 yearsVery useful, thank you, I didn't know you could dump all settings like this.

Jacob Vlijm over 6 years@st01 For (1) you could either sinply run the gsettings command, see if it does the job, or check in dconf editor (not installed by default, but a great tool) if the gsettings key (also) exists. (2) gsettings is the cli frontend to edit the dconf database. Gsettings also checks the integrity of the database, and is therefore preferable to directly editing the dconf database. Since gsettings is higher level, it is slower though. (3), Ah, that is silly :), you are right. Will edit

Nicholas Stommel over 6 yearsThis is superb, thank you so much! Now I can restore my old config when I mess around in gsettings.
