If you're like me and you google lsof -i :3000 or ps aux | grep node | grep -v grep | awk '{print $2}' at least once a month, I built something for you.

# What's on port 3000?
proc on :3000

# Kill it
proc kill :3000

# What ports is node using?
proc on node

# What processes are running in current directory?
proc in .

# Find node processes in current directory
proc by node --in .

# What's running this script?
proc for ./server.py

# Kill multiple things at once
proc kill :3000,:8080,node

Same syntax everywhere: :port, PID, or name.
