List profiles
dconf dump /org/gnome/terminal/legacy/profiles:/
Determine the terminal profile string for the profile you will need. This is the terminal profile that I will export:
[:1430663d-083b-4737-a7f5-8378cc8226d1] foreground-color='#C3C3C7C7D1D1' visible-name='Material Colors' palette=['#070736364141', '#EBEB60606B6B', '#C3C3E8E88D8D', '#F7F7EBEB9595', '#8080CBCBC3C3', '#FFFF24249090', '#AEAEDDDDFFFF', '#FFFFFFFFFFFF', '#00002B2B3636', '#EBEB60606B6B', '#C3C3E8E88D8D', '#F7F7EBEB9595', '#7D7DC6C6BFBF', '#6C6C7171C3C3', '#343443434D4D', '#FFFFFFFFFFFF'] default-size-columns=100 default-size-rows=28 use-system-font=false use-theme-colors=false font='Source Code Pro 10' allow-bold=false bold-color-same-as-fg=true bold-color='#FFFFFFFFFFFF' background-color='#1E1E28282C2C' audible-bell=false scrollbar-policy='never'
And the string that I will need to use to export is
:1430663d-083b-4737-a7f5-8378cc8226d1
The command to export that profile is (note the ending slash)
dconf dump /org/gnome/terminal/legacy/profiles:/:1430663d-083b-4737-a7f5-8378cc8226d1/ > material-theme-profile.dconf
To restore the profile
dconf load /org/gnome/terminal/legacy/profiles:/:1430663d-083b-4737-a7f5-8378cc8226d1/ < material-theme-profile.dconf
dconf list /org/gnome/terminal/legacy/profiles:/ | sed '/^:/!d'
