Ubuntu FAQ: How do I list all of the services on my Ubuntu 16.04 system from the Linux command line?
Answer: Use this command:
service --status-all
Here’s an example of what this looks like on an Ubuntu 16.04.2 LTS system:
root> service --status-all
[ + ] apache-htcacheclean
[ + ] apache2
[ + ] apparmor
[ - ] bootmisc.sh
[ - ] checkfs.sh
[ - ] checkroot-bootclean.sh
[ - ] checkroot.sh
[ + ] console-setup
[ + ] cron
[ + ] dbus
[ - ] hostname.sh
[ - ] hwclock.sh
[ + ] irqbalance
[ + ] keyboard-setup
[ - ] killprocs
[ + ] kmod
[ - ] mountall-bootclean.sh
[ - ] mountall.sh
[ - ] mountdevsubfs.sh
[ - ] mountkernfs.sh
[ - ] mountnfs-bootclean.sh
[ - ] mountnfs.sh
[ + ] mysql
[ + ] networking
[ + ] nginx
[ + ] ondemand
[ - ] plymouth
[ - ] plymouth-log
[ + ] procps
[ + ] rc.local
[ + ] resolvconf
[ - ] rsync
[ + ] rsyslog
[ - ] sendsigs
[ + ] ssh
[ + ] sysstat
[ + ] udev
[ + ] ufw
[ - ] umountfs
[ - ] umountnfs.sh
[ - ] umountroot
[ + ] urandom
[ - ] uuidd
The meaning of the Ubuntu service command output
From the Ubuntu Linux service man page:
service --status-all runs all init scripts, in alphabetical order, with the status command. The status is:
[ + ]for running services[ - ]for stopped services[ ? ]for services without a 'status' command
This option only calls status for sysvinit jobs; upstart jobs can be queried in a similar manner with initctl list.
How to show the Ubuntu version
In a slightly-related note, you can show your Ubuntu version information with the lsb_release -a command:
root> lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.04.2 LTS
Release: 16.04
Codename: xenial
Summary
In summary, if you wanted to see how to list all of the services on an Ubuntu 16.04 system, I hope this is helpful.
