“f0ne.sh” The phone number generator

This script still only works in U.S. cities — international phone numbers are a huge, huge pain, so I don’t see it happening anytime soon; People can edit the script to work for whatever country they live in, but that’s beyond what I’m willing to do.
Updates:

• Interactive mode has a new user interface – colored text!
  
  • ./f0ne.sh
  • (no arguments)
• Command-line arguments – you can now pass arguments to f0ne instead of using the interactive menu system
  
  • USAGE: ./f0ne.sh [city] [style]
  • EXAMPLE: ./f0ne.sh “cleveland, oh” 3
  • OUTPUT: all of the phone nubmers in cleveland – to stdout, so piping is recommended:
  • PIPING: ./f0ne.sh “cleveland, oh” 3 > cleveland.txt
• Can run independent of Crunch
  
  • crunch is VERY fast at generating lists, but not everyone has it.
  • if crunch isn’t found on the user’s system, a substitute shell script is used instead
  • this substitute script is MUCH MUCH slower than crunch; it’s meant as a last-resort.
• Piping to aircrack is still included, but only in interactive mode
• Saves phone numbers to [city].txt instead of the generic “phone.txt”
  
  • So if you asked for “burbank, ca”, the program would save the phone numbers in “burbankca.txt”

I hope that some of you can find this script useful.
