svcs

The svcs command is a command-line tool used in the Solaris and illumos operating systems. It stands for "service status" and is used to display the status of system services.

When executed without any options, it shows a list of all services along with their current states. The states can be either online, offline, degraded, or maintenance.

The svcs command also allows for querying the status of a specific service by specifying its name as an argument. It provides detailed information about the service, including its dependencies, the instances running, and the reason for any faults or errors.

Additionally, the svcs command can be used to enable or disable a service. Admins can use it to stop or start a service manually using the svcadm command or to enable or disable automatic startup at system boot.

The command also supports options like -a to display all services, regardless of their state, and -l to provide even more detailed information about each service.

Overall, the svcs command is a powerful utility for managing and monitoring services in Solaris and illumos, allowing system administrators to troubleshoot and maintain the health of their systems effectively.
