 2) Worth 2 points. Using Linux Shell Scripting. 
    - Implement division by 0, with error trapping, using if and while commands,
       
    How:
    a) using ANY Linux editor, append to your .sh file commands that will do the following:
    b) Append your name, current running date and time to a NEW file called results.txt
    c) Using two variables: FirstNumber and LastNumber, use a while loop.
    d) Ask the user to enter the first number.
    e) Ask the user to enter the second number.
    f) If the user enters the value 99 for the first or the second number, you 
       must exit this section immediately, 
    g) If the second number is ZERO inform the user that you CAN NOT divide by 
       ZERO, and ask for a correct second number.
    h) If the second number is NOT a zero, divide FirstNumber by LastNumber and
       display all numbers on this computation using labels, 
       and append this output to the results.txt file.
    
       example: 4 divided by 1 = 4


 3) - Worth 1 point. Linux Shell Scripting.
      a) MANUALLY download to YOUR computer the file, in the same folder where
         your program in the following question b is located:
         http://users.cis.fiu.edu/~mrobi002/downloads/HumanGenome/VenterGraig/VGuncompressed/hs_alt_HuRef_chr10.fa     

      Using editors, append to your *.sh file, all the commands needed so that 
      when you execute your sh file, this file will produce the following:

      b) Using the file in question a, find out and display the total amount of
         TTT substrings found in the first 2,000 lines in the file in question a

 5 - Worth 2.00 points. Using Windows batch Scripting. 
     topic: Implement division by 0, with error trapping, using if and sumilating 
            while loops
     - Using the NOTEPAD editor, append to the *.bat file, all the commands needed
       so that when you execute your bat file, it will produce the following:

     a) Append your name and class name and section.
     b) Using two variables: FirstNumber and LastNumber, 
     c) Ask the user to enter the first number.
     d) Ask the user to enter the second number.
     e) If the user enters the value 66 for the first or the second number, you 
        must exit the loop immediately, and terminate this section ONLY.
     f) If the second number is ZERO inform  the user that you CAN NOT divide by
        ZERO, and ask for a correct second number.
     g) If the second number is NOT a zero, do the division, display all numbers
        of this computation using labels,
         
        example: 4 divided by 1 = 4
        
        
        
Rename your *bat file to *ba
