The Bash script must display the students letter grade based on the numeric average of combined test scores. The script should prompt user to enter numeric grades (test scores). Apply the loop structure to the portion of the script where the user is asked to enter the numeric grades. The script should also display the current date and time in Knoppix Linux.
Update the given script for above requirements, and also give a pseudo code for the script logic.
The appropriate letter grade for the number grade, should be computed using this scale:
90 to 100: Display a letter grade of "A"
80 to 89: Display a letter grade of "B"
70 to 79: Display a letter grade of "C"
65 to 69: Display a letter grade of "D"
0 to 64: Display a letter grade of "F"
