# List All Services Managed By Brew Daemonized services, such as PostgreSQL, can be installed and managed with Homebrew. Under the hood `brew` uses `launchctl` on Mac to manage these services — i.e. starting, restarting, and stopping them. Assuming you've already installed some services, you can run `brew services list` to see what services there are and what their current status is. ```bash $ brew services list Name Status User File mailhog none mysql none postgresql@11 started jbranchaud ~/Library/LaunchAgents/homebrew.mxcl.postgresql@11.plist postgresql@13 none postgresql@16 none unbound none ``` This is the default behavior if you just run `brew services` without a subcommand. This is helpful if you are, for instance, trying to see which PostgreSQL server version you are currently running and which other ones are available to run. I might then issue a `stop` to `postgresql@11` so that I can then `start` the `postgresql@16` service. See `brew services --help` for more details.
