#
# CHANGE LOG
#
# revision 6 changes: (8/22/10)
#  -command-line arguments!
#   -to run: ./f0ne.sh [city] [style]
#  -outputs only phone numbers instead of a file (so user can pipe to a file or aircrack)
#  -ex: ./f0ne.sh "albuquerque, nm" 2
#   -this will create all alb numbers with style 555-666-1234 (- separators)
#
#
# revision 5 changes: (8/18/10)
#  -can run independent of crunch - slower, but it works if crunch isn't available
#  -saves to 'name_of_city.txt' instead of generic 'phone.txt'
#  -leeto burrito ascii art
#
# revision 4 changes:
#  -removes duplicates for numbers that don't contain the area code (prefix only)
#
# revision 3 changes:
#  -aircrack-ng passthrough for WPA cracking (saves time/space)
#    -key is outputted to aircrack.txt and script stops immediately if key is found 
#
# revision 2 changes:
#  -menu system to output certain phone number formats
#  -corrected error for cities with spaces in the name
#
############################################################################
#
# ToDo
#   receive city, format, aircrack info as arguments to be more linux-like
#    - just have if [[ $1 != ... everywhere!
#
############################################################################
#
# Note:
#   This script runs MUCH faster if crunch is installed!
#   program looks for crunch in directory /pentest/passwords/crunch/
#   edit the line below if crunch is located elsewhere on your computer:
#
CRUNCH="/pentest/passwords/crunch/./crunch"
#CRUNCH="/derpderp/hurrdurr/./crunch" # for testing if user doesn't have crunch
#
#   crunch can be found here: http://sourceforge.net/projects/crunch-wordlist/
