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:

• [ + ] running services
• [ - ] stopped services
• [ ? ] 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.
