Grades exercise

Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!

1. The problem statement, all variables and given/known data:

Write a shell script program that will input a name and a mark between 0 and 100. The program then displays the name, the mark, and a letter grade for the mark, as per the following grade cut formula.

2. Relevant commands, code, scripts, algorithms:

case/read/echo/if

3. The attempts at a solution (include all code and scripts):

I have a program that i need to get done that gets the person's name and his grade then prints it in this order "name-grade-gradeletter" so i wrote this code:

Code:

#!/bin/bash
while :; do
read -p "Enter the person's name: " name
read -p "Enter the grade of the person: " grade

case $grade in
[50-59]) echo "$name $grade F";;
[60-69]) echo "$name $grade C";;
[70-79]) echo "$name $grade B";;
[80-100]) echo "$name $grade A";;
*) echo "Wrong input"

esac
done
echo "Goodbye"

So when you input the name and the grade, it just skips to the asterisk and outputs "Wrong input". Shouldn't it go through the values since the case is $grade and is using grade that is given by the person ?

Can someone tell me my mistake ?

P.S i tried changing the case to if command to see if it works but it shows me that no such file exists ?:

Code:

if [$grade >= 50||$grade < 60]; then
echo "$name $grade F"
elif [$grade >= 60||$grade < 70]; then
echo "$name $grade C"
elif [$grade >= 70||$grade < 80]; then
echo "$name $grade B"
elif [$grade >= 80||$grade <= 100]; then
echo "$name $grade A"
else
echo "Wrong input"
fi

4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):

Sheridan college, Oakville, canada, Syed tanbeer, ["https://academics.sheridancollege.ca/programs/computer-systems-technology-software-development-and-network-engineering"

debconf-mergetemplate

DEBCONF-MERGETEMPLATE(1)					      Debconf						  DEBCONF-MERGETEMPLATE(1)

NAME

       debconf-mergetemplate - merge together multiple debconf template files

SYNOPSIS

	debconf-mergetemplate [options] [templates.ll ...] templates

DESCRIPTION

       Note: This utility is deprecated. You should switch to using po-debconf's po2debconf program.

       This program is useful if you have multiple debconf templates files which you want to merge together into one big file. All the specified
       files will be read in, merged, and output to standard output.

       This can be especially useful if you are dealing with translated template files. In this case, you might have your main template file, plus
       several other files provided by the translators. These files will have translated fields in them, and maybe the translators left in the
       english versions of the fields they translated, for their reference.

       So, you want to merge together all the translated templates files with your main templates file. Any fields that are unique to the
       translated files need to be added in to the correct templates, but any fields they have in common should be superseded by the fields in the
       main file (which might be more up-to-date).

       This program handles that case properly, just list each of the translated templates files, and then your main templates file last.

OPTIONS

       --outdated
	   Merge in even outdated translations. The default is to drop them with a warning message.

       --drop-old-templates
	   If a translation has an entire template that is not in the master file (and thus is probably an old template), drop that entire
	   template.
