'''Systemctl''' is a '''systemd''' utility that is responsible for Controlling the '''systemd''' system and service manager. '''Systemd''' is a collection of system management daemons, utilities, and libraries which serves as a replacement of '''System V init''' daemon. Systemd functions as central management and configuration platform
 +
 +
To list all loaded services on your system (whether active; running, exited or failed, use the '''list-units''' subcommand and <code>--type</code> switch with a value of service.
 +
# systemctl list-units --type=service
 +
OR
 +
# systemctl --type=service
 +
 +
 +
But to get a quick glance of all running services (i.e all loaded and actively running services), run the following command.
 +
# systemctl list-units --type=service --state=running
 +
OR
 +
# systemctl --type=service --state=running
 +
 +
 +
List all failed units.
 +
# systemctl --failed
 +
    +
Check whether a Unit or Service is running or not?.
 +
# systemctl status httpd-e-smith
    +
 +
How do I start, restart, stop, reload and check the status of a service ('''httpd.service''') in Linux.
 +
# systemctl start httpd-e-smith.service
 +
# systemctl restart httpd-e-smith.service
 +
# systemctl stop httpd-e-smith.service
 +
# systemctl reload httpd-e-smith.service
 +
# systemctl status httpd-e-smith.service
