On Debian (but not Fedora or RHEL), to see a list of all “master alternative names”:
update-alternatives --get-selections
--get-selections
list master alternative names and their status.
And for each of those listed, you can run --list $ALTERNATIVE_NAME
, e.g.
update-alternatives --list editor
--list name
Display all targets of the link group.
If you would like to see a list of all alternatives in their respective groups, you could run the following in fish
shell:
for alternative in (update-alternatives --get-selections)
echo $alternative
update-alternatives --list (echo $alternative | cut -d" " -f1)
echo
end | pager
The (ba|z)?sh syntax should be something similar.
To change the alternatives, run sudo update-alternatives --config $ALTERNATIVE_NAME
