Wow, thanks. I did not know how that worked. So basically, it works like CSS sort of, as long as I mention the file name at the end, it will look in those files for the input?
Just want to be sure I understand fully.

I kind of figured it out from looking again but am still confused on a couple of things:
the first line is basically telling the script to get input from first file, creating and storing the array, weight[] which holds the values as such: weight[Homework:0.10, Lab :0.30, Quiz:0.40, Final :0.15, Survey:0.05]
Ok, I think i have the basics of how to use the two files then. So, using the snippet of code you posted gives the total points for each student, but how do I divide those by 575.25 to get the final percentile score for each student?
I have tried a few things and none seem to work. have tried to do SUM[$1]/575.25... Illegal array reference error
have tried to say x=SUM[s]/575.25 at end, but just got 0 all the way down the list and saying x=SUM[s]/575.25 returned a single name and a 0...
I got 575.25 outside of the script. There are 7 Homework assignments, 7 Labs, 7 Quizzes and 1 Final with a total of 100 points possible on each. Then there is the survey worth a possible 5 points.
Knowing the weighted values:
Homework 10%
Labs 30%
Quizzes 40%
Final 15%
Survey 5%
I applied that to the possible total scores, as well
Homework --> 700*0.1 = 70
Labs --> 700 * 0.3 = 210
Quizzes --> 700 * 0.4 = 280
Final --> 100 * 0.15 = 15
Survey --> 5 * 0.05 = 0.25
all weighted percentage values equal 100, so it is good there. so I added the totals 70+210+280+15+.25 = 575.25
I was able to, using the code snippet you provided, divide the totals by the 575.25 and get the final weighted percentile score for each student. I then spent the next several hours trying to get a letter grade assigned to each one based on the percentile score, but had no luck. It currently gives everyone an 'A' no matter what their percent score was, which I am sure a student would like, but not going to work for me...lol.
Very frustrating, trying to learn awk on the fly like this. ... Here is the most current version of the code I have with various comments on why/what is going on:
Adding output and noticed that the student I said deserves an A actually deserves an A-....
Output:
Name Percent Grade
Sam 60.75 A
Chelsey 93.34 A
Andrew 69.99 A
Shane 74.36 A
Ava 75.53 A
Wow, very simple. But why wouldn't it work the way I was trying? (Using an if/else block)
What does the 'R' represent in the second arg for the function?
Request your help to change the field color based on condition , if it is otherthan 0. using html in unix.

In the awk below I am trying to copy the entire contents of $6 there may be multiple values seperated by a ;, to $8, if $8 is . (lines 1 and 3 are examples). If that condition $8 is not .

In the perl below, which does execute, I am having trouble with the else in Rule 3. The digit in f{8} is extracted and used to update f accordinly along with the value in f.
There can be either - * or + before the number that is extracted but the same logic applies, that is if the value is greater... (5 Replies)
I am trying to output a tab-delimited result that uses the data from a tab-delimited file to combine and subtract specific lines.

Hi everybody,
I'm trying to replace the $98 field with "T" if the last field (108th) is T
