• Ping host without trying to lookup symbolic names for addresses:
  ping -n "{{host}}"
• Ping host and ring the bell when a packet is received (if your terminal supports it):
  ping -a "{{host}}"
• Ping host and prints the time a packet was received (this option is an Apple addition):
  ping --apple-time "{{host}}"
