Problem with getting awk to multiply a field by a value set based on condition of another field
Hi,
So awk is driving me crazy on this one. I have searched everywhere and read man, docs and every related post Google can find and still no luck. The actual files I need to run this on are sensitive in nature, but it is the same thing as if I needed to calculate weighted grades for multiple students using all assignments as input. (Sample below)
The input file is a csv. I took all of the assignment names from $3 and calculated the highest grade, lowest grade and average grade for each one. the code I used to do this is:
That gave me the desired out put. Using the same input file, I want to now group by the Student name and then give weight to each assignment grade.
so the logic is this: If $2 = "Homework" then $4 = $4*0.10 and so on for each assignment Category. The all I need to do is sum all of the $4 for each student individually. On top of this, I also need to assign a letter grade based on the value of each student's total class grade, so I am not sure even how to proceed there at all.
However, I cannot make this happen and return all kinds of goofy results, including somehow printing the output headers several times with nothing else and they are set before anything else and are no where near a loop. So, I am totally confused. Here is the most recent failure:
So, if anyone can help me out here, I would appreciate it.
I want to find the top N entries for a certain field based on the values of another field.
For example if N=3, we want the 3 best values for each entry:
Entry1 ||| 100
Entry1 ||| 95
Entry1 ||| 30
Entry1 ||| 80
Entry1 ||| 50
Entry2 ||| 40
Entry2 ||| 20
Entry2 ||| 10
Entry2 ||| 50... (1 Reply)

but that doesn't do anything
also tried

In the tab-delimeted input file below I am trying to use awk to update the value in $2 if TYPE=ins in bold, by adding the value of
HRUN= in italics. In the below since in line 1 TYPE=ins the 117282541 value in $2 has 6 added because that is the value of HRUN=.
Hopefully the awk is a start but I... (2 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.
If $4 matches in each line then the first matching sequential $6 value is added to $2, unless the value is 1, then the original $2 is used (like in the case of line... (3 Replies)
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)
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 .
