I have these users setup on my single-user machine and I'd like to delete unnecessary ones to make the list shorter:
$ cut -d: -f1 /etc/passwd
root
daemon
bin
sys
sync
games
man
lp
mail
news
uucp
proxy
www-data
backup
list
irc
gnats
nobody
systemd-timesync
systemd-network
systemd-resolve
systemd-bus-proxy
syslog
_apt
messagebus
uuidd
lightdm
whoopsie
avahi-autoipd
avahi
dnsmasq
colord
speech-dispatcher
hplip
kernoops
pulse
rtkit
saned
usbmux
rick
vnstat
nvidia-persistenced
guest-atkb2q
guest-u4sf2i
guest-rmlbtg
guest-mz53vp
Off the top of my head I'm think I should delete users:
games
mail
news
uucp
proxy
www-data
backup
list
irc
gnats
systemd-timesync
systemd-network
whoopsie
avahi-autoipd
avahi
dnsmasq
speech-dispatcher
hplip
kernoops
rtkit
guest-atkb2q
guest-u4sf2i
guest-rmlbtg
guest-mz53vp
But before bricking my system I'm wondering?
- How to delete the files they own at the same time
- What apps created these users and how to remove them too
- Did I miss some users to delete
- Will I be deleting users I shouldn't
I appreciate Ubuntu Bloatware created some of these users and there are many many Ubuntu apps I don't use.
