# Purpose:      Converts numbers from one base to another

# Author:       hgate73 (linuxquestions.org)

# Structure:
# $1 is base of number being converted (-d, -h, -b, -o)
# $2 is number to convert
# $3 is base of number to convert to  (-d, -h, -b, -o)
# Example: ./bConvert.sh -d 3 -b    will convert the decimal (-d for DECIMAL) number 3 to binary (-b for BINARY). It should result in 11

# This is to make sure the input value is in upper-case if it is a letter
