I installed MySQL but I am unable to see if it is running or has stopped. How do I see what are the currently running services corresponding to the "Services" interface in Windows?
$ sudo launchctl list
For example only MySQL you can filter the output of the command above, like
sudo launchctl list | grep -i mysql. Note
-i is to make the filter case insensitive.
There are some other "services", that will install themselves in:
For those, there is a command like
$ ps -ef |grep /Library/StartupItems to view whether it is loaded and running. But there isn't a generic mechanism to stop, start or restart.
In which category your MySQL installation falls is impossible to say, as your question is lacking details on what exactly you have installed, what its source is, how it was installed, etcetera.
