AFP – List of connected users & IPs

I was recently asked at work to write a small script that would restart AFP once a week. My boss wanted to get an e-mail with a list of the currently logged in users to AFP along with their respective IP addresses. This is a messy one liner to get most of the information, but it gets the job done:

sudo serveradmin command afp:command = getConnectedUsers | egrep '(ipAddress)|(name)' | sed '$!N;s/\n/ /' | cut -d '"' -f 2,4 | tr '"' '\t'

Here’s the full script:
