Bash shell script

Need some help with some very basic Bash shell scripts to get me going. 1: Write a script where the user can enter two numbers. Print if the numbers are equal, not equal, greater than or less than another. 2: Write a script that tries to open the file [login to view URL], check if the file exists, if it is readable or writeable. 3: Write a script that prompts the user for a number between 1 and 10, if the user enters a number outside this area shall have an fault comments of the script. 4: Make a review informs script! In one file is the score for each question, one point per line. The script will add up the points and return what grade to be added. G = 30, VG = 48 5: Experiment on your own and write one scripts based on these questions.
