Maybe I could tab complete systemctl, but I don't currently have a
CentOS 7 system to test on.
maybe you should just install CentOS inside a VM and test it
[root@srv-rhsoft:~]$ systemctl restart h
halt-local.service haveged.service home.mount
hostapd-guest.service
httpd-lounge-worker.service hybrid-sleep.target
halt.target hibernate.target
hostapd-guest-interface.service hostapd.service httpd.service
The real issue is that I have to know (in the above example) that it is
httpd not http.
With so many systems, distros, and services it is hard to remember every
service name exactly (and some names are very long). For example ntpd
has a d, but nfs does not.
Tab completion fixes this issue for me.
How can I use tab completion with systemd?
as like for any other software - hit the TAB key

2. How to find all possible services:
The init way:
ls -l /etc/init/d
The systemd way:
ls -l /lib/systemd/system/*.service /etc/systemd/system/*.service
This seems WAY harder and I have to remember 2 locations instead of 1
nobody but you installs systemd-units in /etc/ and so you have only one
location AND customized ones - with sysvinit you
had no way to override /etc/init.d/httpd without doing the work after each
update again
Harald,
Thank you for your reply and time.
I will make some time at some point to install CentOS 7 again, I just don't
have one installed right now.
#1 I did not know you could tab complete that way! i.e. as part of a command
argument, not just as part of a path.
Guess I learned something new after 20 years :)
#2 I can see the advantages of having a local override just like /usr/bin has
/usr/local/bin.
Out of curiosity is there a reason the team did not follow the local pattern
with something like: /lib/systemd/local/system?
It is easy enough to create an alias on systems I use often, it will just take time to learn/memorize the new paths, I
am so used to /etc/init.d.
