Very few things running here. BTW, I will never understand why a lot of people "cat" a file and then pipes it to "grep" instead of "grepping" the file directly :)

To be fair I used to do it, too. 🚂 It reveals your line of thought: “First, I need to open the file.” ⇒ Let’s write this down now. Specifying the pathname at the end of the command line is arguably “unintuitive”.​

Holy carp, how’d you spot this? It wouldn’t’ve crossed my mind in a million years. 🚁 To show deviations from the default (/etc/defaults/rc.conf) you can use sysrc(8), the advantage being that it takes account of any /etc/rc.conf.d/*, too. (My setup uses service‐specific *.conf files.)​
Bash: 
sysrc -a | egrep '_enable: ([Yy][Ee][Ss]|[Tt][Rr][Uu][Ee]|[Oo][Nn]|1)$' # cmp. checkyesno in /etc/rc.subr
However, the question​

is actually answered with service(8)​
Bash: 
service -e # just a list of enabled services, not necessarily currently running
presuming that you ran all your services on one bare‐metal machine, though. 🚠​

Frankly, this just sounds dumb. Don’t run services you don’t need. 🛳️ If you really have excess energy/bandwidth, though, how about running a TOR exit node? Just to name an example.​

There is actually a good reason for this, when writing complex shell pipelines. It makes for more readable code if you format them roughly like this (perhaps with some better indentation):

sh: 
cat input.foo | \
grep bar | \
awk 'something' | \
...
blatz another operation | \
fish fred > \
    output.file

Like that one can see all the operations that are being done, and each line except the last starts with the name of the program being run.
 
Here's what's running on mine:
Code: 
clear_tmp_enable: YES
dumpdev: NO
geli_autodetach: NO
ntpd_enable: YES
ntpdate_enable: YES
nut_enable: YES
nut_upsmon_enable: YES
pf_enable: YES
powerd_enable: YES
samba_server_enable: YES
smartd_enable: YES
smfand_enable: YES
sshd_enable: YES
sshguard_enable: YES
wsddn_enable: YES
zfs_enable: YES
zfsd_enable: YES

Everything's from the standard packages except for wsddn (author provides a standalone package file) and smfand (which is my own custom script for managing the fans on my machine).

I do it as well, because it's arguably more intuitive when chaining things together, as mentioned above.

# cat /etc/rc.conf | grep "YES" | sort

makes more sense to me than
# grep "YES" /etc/rc.conf | sort

What if I want to sort first?
# cat /etc/rc.conf | sort | grep "YES"

Whereas to do it the other way I have go look up the syntax of sort, because in 30 years of using UNIX and UNIX-like systems I can count on both hands the number of times I've ever ran sort without using a pipe. And don't get me started on the syntax for ln.

Run a lot of different things on FreeBSD: ZFS, Poudriere, OpenNTPD, CoreDNS, bHyve, vm-bhyve (now part of base), jails, Monit, M/Monit, Caddy, Uptime Kuma, Prometheus, Syslog-NG, rsyslog, Apache, Nginx, NSD, Wireguard, pf, ipfw, netdata, syncthing, OpenLDAP, Postfix, SaltStack, acme.sh, Zeek, dnsdist and Step CA. Also run OPNSense firewalls. It is 1 big playground!
