Explanation / Answer

Write your name in place of your_name in the code:

Here is the program2.sh file:

#!/bin/bash

echo your_name > results.txt
today=`date '+%Y-%m-%d--%H:%M:%S'`;
echo $today >> results.txt

echo "Please enter a number:"
read number
while [ $number -lt 1 ] || [ $number -gt 50 ];do
   echo "Please enter a number:"
   read number
done
i=1
sum=0
#I am assuming the user-input number has to be included in the sum
while [ $i -lt `expr $number + 1` ];do
   sum=`expr $sum + $i`
   ((i++))
done
echo $sum
echo $sum >> results.txt
