Handling Services

TODO SECTION

This section describe the (correct) way to handling services, such as starting, stoping, restarting, etc. SME is different compared with other linux distributions, so service are handled in a different maner.

General handling

sv t servicename

service servicename action

Apache Service

Restarting:

sv t httpd-e-smith

service httpd restart
