Kitchen converge usually takes a lot of time to complete. Sometimes I leave it running and forget about it, so I created aliases that notify me when kitchen has finished.

alias kc="kitchen converge; osascript -e 'display notification \"Kitchen converge finished\" with title \"Kitchen Converge finished\"'"
alias kd="kitchen destroy; osascript -e 'display notification \"Kitchen destroy finished\" with title \"Kitchen Destroy finished\"'"
alias kv="kitchen verify; osascript -e 'display notification \"Kitchen Verify finished\" with title \"Kitchen Verify finished\"'"
alias kt="kitchen test; osascript -e 'display notification \"Kitchen Test finished\" with title \"Kitchen Test finished\"'"
