Reading 5 Students names and grades using while loop????
How do I write a shell script file to read 5 student names (First and Last name) and their grades using a While Loop? Find the Average, Maximum, and Minimum of grades using the same While Loop. Prompt the user using tput to enter the information (first name, last name, grade). Save the data in a file called students.txt. Sort the file by last name and display it on the screen. Someone gave me this to go buy but im way basic and am not sure if there is anything missing from this. I also need to be able to use Tput.
If anyone can help me get this done or tell me whats missing id appreciate it.
1. suppose file is of form "Name Surname Grade"
#!/bin/zsh
sum=0
min=10000
max=0
n=5
i=0
file="students.txt"
cat $file | while read line; do
set line
grade=$3
sum='expr $sum + $grade'
if [ $grade -gt $max ]; then
max=$grade
fi
if [ $grade -lt $min ]; then
min=$grade
fi
i='expr $i + 1'
if [ $i -ge $n ]; then
break
fi
done
average='expr $sum / $i'
echo "Max: $max Min: $min Avg: $average"

POE::Test::Loops(3pm) User Contributed Perl Documentation POE::Test::Loops(3pm)
NAME
POE::Test::Loops - Reusable tests for POE::Loop authors
SYNOPSIS
#!/usr/bin/perl -w
use strict;
use Getopt::Long;
use POE::Test::Loops;
my ($dir_base, $flag_help, @loop_modules, $flag_verbose);
my $result = GetOptions(
'dirbase=s' => $dir_base,
'loop=s' => @loop_modules,
'verbose' => $flag_verbose,
'help' => $flag_help,
);
if (
!$result or !$dir_base or $flag_help or !@loop_modules
) {
die(
"$0 usage:
",
" --dirbase DIR (required) base directory for tests
",
" --loop MODULE (required) loop modules to test
",
" --verbose show some extra output
",
" --help you're reading it
",
);
}
POE::Test::Loops::generate($dir_base, @loop_modules, $flag_verbose);
exit 0;
DESCRIPTION
POE::Test::Loops contains one function, generate(), which will generate all the loop tests for one or more POE::Loop subclasses.
The "SYNOPSIS" example is a version of poe-gen-tests, which is a stand-alone utility to generate the actual tests. poe-gen-tests also
documents the POE::Test::Loops system in more detail.
FUNCTIONS
generate( $DIRBASE, @LOOPS, $VERBOSE )
Generates the loop tests. DIRBASE is the (relative) directory in which a subdirectory for each of the LOOPS is created. If VERBOSE is set
to a TRUE value some progress reporting is printed.
POE::Test::Loops::generate(
"./t",
[ "POE::Loop::Yours" ],

);
