awk 'BEGIN     { print "Name           Exam1           Exam2           Exam 3        Total        Grade" }' grades | tee gradesorted

Waarom twee awk programma's?

awk '{if ($2+$3+$4<50){grade="F"}else if ($2+$3+$4>49 && $2+$3+$4<65)
{grade="D"}else if ($2+$3+$4>64 && $2+$3+$4<80){grade="C"}
else if ($2+$3+$4>79 && $2+$3+$4<90){grade="B"}else{grade="A"}}
{print $0, "          ", $2+$3+$4, "          ", grade;}' grades | tee gradesorted

Code:

#!/bin/sh

awk 'BEGIN {
   format = "%-15s%-15s%-15s%-15s\n"
   printf format, "Name", "Exam1", "Exam2", "Exam 3", "Total", "Grade"
  }
{
 total = $2 + $3 + $4
      if (total < 50) {grade = "F"}
 else if (total < 65) {grade = "D"}
 else if (total < 80) {grade = "C"}
 else if (total < 90) {grade = "B"}
 else {grade="A"}
}
{printf format, $1, $2, $3, $4, total, grade}' grades > gradesorted

Pipe de printf via sort:

Code:

awk 'BEGIN {
   format = "%-15s%-15s%-15s%-15s%-15s%-15s\n"
   printf format, "Name", "Exam1", "Exam2", "Exam 3", "Total", "Grade"
  }
{
 total = ( $2 + $3 + $4 ) / 3 # I think you want the average
      if (total < 50) grade = "F"
 else if (total < 65) grade = "D"
 else if (total < 80) grade = "C"
 else if (total < 90) grade = "B"
 else grade="A"

 format = "%-15s%-15s%-15s%-15s%-15d%-15s\n"
 printf format, $1, $2, $3, $4, total, grade | "sort"
} ' grades > gradesorted
