# List Services
All possible services are in:
> ls /etc/sv
The computer only uses those in /var/service, so symbolic links are made to start and stop services.
> ls /var/service
# Start Services
Enable the sshd service, so that ssh will work every time you boot up:
> sudo ln -s /etc/sv/sshd /var/service
Then start the service:
> sudo sv start sshd
# Stop Services
Stop `mpd` with:
> sudo sv stop mpd
And stop it starting at startup with:
> sudo rm /var/service/mpd
You can also just make a file called 'down':
> sudo touch /var/service/mpd/down
This means you can start and stop the service without making symbolic links, but mpd will be 'down' when the computer starts.
# Making a Service
Look in the `/etc/sv` directory, then in the existing services' 'run' files.
You'll find a simple dash script (therefore Posix compliant).
You can write your own, just stick in the shebang `#!/bin/sh`.
If unsure, use `#!/bin/bash` as the first line. When Void Linux says `sh`, it means `dash` shell, not `bash`.
Confirm the shell you'll use:
> ls -l $(which sh)
