Command to List Installed and Enabled GNOME Extensions

I want a command to list all extensions currently installed. Also, a command to list all enabled extensions.

Is this possible?

Your locally installed gnome Shell extensions, i.e., these that are installed for your user only, can be listed with the commmand:

ls ~/.local/share/gnome-shell/extensions/

You can find out which extensions are enables by querying a dconf setting:

gsettings get org.gnome.shell enabled-extensions

System wide installed gnome-shell extensions are listed with the command

ls /usr/share/gnome-shell/extensions/

This command:

gnome-extensions list

will show all extensions enabled and disabled. To only show those extensions which are enabled use the command:

gnome-extensions list --enabled
