+# Service Management (systemd)
+
+`systemd` is a **System** Management **D**aemon which replaces the sysvinit process to become the first process with PID = 1, which gets executed in user space during the Linux start-up process. It is a system that is designed specifically for the Linux kernel. It is now being used as a **replacement of init.d** to overcome shortcomings of it. It uses `systemctl` command to perform related operations.
+
+e.g. `$ systemctl start [service-name]`, `$ systemctl poweroff`
