Comment 14 for bug 1463072

For my reference later.
The 'dconf read' with ':list' syntax has changed, so the comments above don't work in 18.04.

Updated, this worked for me:

$ dconf list /org/gnome/terminal/legacy/profiles:/
:b1dcc9dd-5262-4d8d-a863-c897e6d979b9/

$ dconf write /org/gnome/terminal/legacy/profiles:/:b1dcc9dd-5262-4d8d-a863-c897e6d979b9/word-char-exceptions '@ms "-=&#:/.?@+~_%;"'

For a copy and paste single line, that'd look like this:

$ for profid in $(dconf list /org/gnome/terminal/legacy/profiles:/); do dconf write /org/gnome/terminal/legacy/profiles:/${profid%/}/word-char-exceptions ; done
