Changing themes in command lines

 * Cinnamon version 5.0.5
 * Distribution - Mint 20.2

Issue

Hi, I'd like to automatise switching from one theme to another but I can't seem to find any command line to do so.

Expected behaviour

I was thinking of two solutions :

1. A couple of Cinnamon commands that has the exact same effect that the themes settings GUI (if it exist).
2. A couple of commands to move some config files around and then refresh Cinnamon.

But I can't think of any way to do either 1 or 2. I'm open to any idea from you kind folks.

Thanks in advance.

For 1. A command to change the theme would be gsettings set org.cinnamon.theme name "Linux Mint" You can see what other settings can be changed in this way by using dconf program

@fredcw Thank you very much !

It's exactly what I needed. For information, here is what I used to change the current theme to Mint-Y-Dark :

gsettings set org.cinnamon.desktop.interface icon-theme "Mint-Y-Dark"
gsettings set org.cinnamon.desktop.interface gtk-theme "Mint-Y-Dark"
gsettings set org.cinnamon.theme name "Mint-Y-Dark"
~/.conky/conky-grapes/create_config.py -ri lightgreen -ti green -te lightgrey
xdotool key ctrl+alt+"Escape"

• The 4th command change the theme of a conky that I use (optional).
• The 5th is a keyboard shortcut "cheat" included in Mint to refresh Cinnamon (don't know if it's present in other distros).
• I never change cursor but I guess it will be gsettings set org.cinnamon.desktop.interface cursor-theme.
• Neither the borders but this one I haven't found.

Currently I use a script containing these 4 lines with cron to switch between different themes at different hours of the day. The next step will be for me to make a script that get the time and select the desired theme relatively to a time range.

If some are interrested I'll post the final result here when I'll be done.

How about that update?

What about changing the menu icon?
