That actually helps alot, as I had tried something like that. What I tried to do was:
That did not work, but by storing the weights in in an array, I see how it could be workable. My only question is how to store/use multiple values.
If $2 = Homework then $4 needs to be multiplied by 0.1
if $2 = Quiz then $4 needs to be multiplied by 0.4
if $2 = Lab then $4 needs to be multiplied by 0.3
if $2 = Final then $4 needs to be multiplied by 0.15
if $2 = Survey then $4 needs to be multiplied by 0.05
Then, all I would need to do is some $4 with the new values and have the overall percent for each student.
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)

Hi everybody,

I am trying to confirm the counts from another code and tried the below awk, but the syntax is incorrect. Basically, outputting the counts of each condition in $8. Thank you :)

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

I am trying to output a tab-delimited result that uses the data from a tab-delimited file to combine and subtract specific lines.

ROAD(7) Miscellaneous Information Manual ROAD(7)NAME
road, gps - road map of the United States
SYNOPSIS
games/road [ -g ] [ -s scale ]
games/gps
DESCRIPTION
Road displays a road map centered around some specified place in the United States. The data comes from the Census Bureau Tiger Database.
The map is drawn in three shades of grey. Light grey is used for water features such as rivers, streams and lakes. Dark grey is used for
railroads and airports. Black is used for roads. On terminals with ldepth zero, all shades appear black.
Without options, the center of the map is the latitude and longitude specified in the file /lib/sky/here. If the -g option is given, the
center of the map will be the latitude and longitude specified by continually monitoring the end of the file /tmp/gpslog. This file is
written by the GPS satellite receiver program gps. With this option, and with gps running, road becomes a moving map display suitable for
cars or planes.
Keyboard commands
s number
sets the scale of the map to number. The number can be prefixed with + or - to increase/decrease the current scale. Scale 6 is
about one mile across the screen and scale 10 is about ten miles across. Scales 1 through 10 are drawn with maximum detail showing
all roads, trails, rivers, streams and airports. Scales 11 through 14 show highways, rivers, airports and county boundaries.
Scales 15 through 20 show interstate highways and state boundaries.
/regexp
All features labeled by text matching the regular expression are highlighted.
p place
centers the map at the specified place. Usually the place must have the associated state code, (eg murrayhill,nj) but places like
lax and ewr are also known.
l latitude longitude
centers the map at the specified coordinate.
g toggles the -g option described above.
q Exit.
Mouse button commands
Button 1
displays the text of the line nearest the cursor. Normally this is the name of a street or river.
Button 2
displays the text of the place nearest the cursor. Normally this is a town.
Button 3
centers the display on the cursor position.
Gps reads /dev/eia0 assumed connected to a Garmin GPS-55 satellite receiver and writes the current location on the end of the file
/tmp/gpslog. It is intended to be used with mobile PC's.
FILES
/lib/roads/LLLL/LLLLGGGG.h
scale 1-10 database files where LLLL is the latitude multiplied by 5 and GGGG is the longitude multiplied by 5.
/lib/roads/LLL/LLLGGG.h
scale 11-14 database files where LLL is the latitude multiplied by 1 and GGG is the longitude multiplied by 1.
/lib/roads/LL/LLGG.h
scale 15-20 database files where LL is the latitude multiplied by 0.2 and GG is the longitude multiplied by 0.2.
/lib/roads/place
/lib/roads/place.local are the translations between place names and locations. These files must be sorted.
/lib/sky/here
default starting map center.
/tmp/gpslog
moving map location.
