Looking up to my term, I saw this:
lebowsky@pc : <no command here>
lebowsky lightdm rpcuser
avahi mail rtkit
bin mpd saned
brltty named sddm
colord nbd systemd-coredump
cups nobody systemd-journal-remote
daemon ntp systemd-network
dbus openvpn systemd-oom
deluge partimag systemd-resolve
dhcpcd polkitd systemd-timesync
dnsmasq postgres tss
ftp pyuser usbmux
geoclue qemu users
git root uuidd
http rpc
What key did I hit with my elbow ?
