systemd/src/hostname/hostnamectl.c
Lennart Poettering 2bf618331d hostnamectl: add -j switch for quick json output 
We already support -j as shortcut for JSON mode in various tools. Let's
add one more. We probably should add this systematically (at least where
it doesn't conflict with an existing -j switch with other purpose). But
I am too lazy to add that now.
