# Create a BASH script (guessing-game.sh) that uses the provided function to generate 
# a pseudo-random number between 1-100 stored in NUMBER: 
#           NUMBER=$[ ( $RANDOM % 100 )  + 1 ] 
# The user should be asked to guess the number ($GUESS) and be told if they are too high 
# ($GUESS > $NUMBER) Òtoo highÓ, or if they are too low ($GUESS < $NUMBER) Òtoo 
# lowÓ. If the user guesses the correct number then they are told that they have won and the 
# program exits. (Ctrl-C Ð force terminates).  Extension: Give the user a maximum of 8 
# guesses before the program says that they have lost. If the user loses or wins, they should be 
# asked if they would like to play again. If the user enters a guess of ÒqÓ the script should exit.
