Find minimum and maximum values based on column with associative array
Hello,
I need to find out the minimum and maximum values based on specific column, and then print out the entire row with the max value.
I have tried this one:
and I only get
Note column 6 is the common field for keys of the associative array I was trying. The problem is with the min[$6], which is always set to 0 by default. Any help is greatly appreciated!
I'm at wits end with this issue and my troubleshooting leads me to believe it is a problem with the file formatting of the array referenced by my script:
awk -F, '{if (NR==FNR) {a=$4","$3","$2}\
else {print a "," $0}}' WBTSassignments1.txt RNCalarms.tmp
On the WBTSassignments1.txt file... (2 Replies)

PEXTREM(1) General Commands Manual PEXTREM(1)NAME
pextrem - find minimum and maximum values in RADIANCE picture
SYNOPSIS
pextrem [ -o ] [ picture ]
DESCRIPTION
Pextrem locates the minimum and maximum values for the input picture, and prints their pixel locations and color values. The first line
printed contains the x and y pixel location (x measured from the left margin, y measured from the bottom), followed by the red, green and
blue values. The second line printed contains the same information for the maximum value.
The -o option prints the original (radiance) values, undoing any exposure or color correction done on the picture.
If no input picture is given, the standard input is read.
AUTHOR
Greg Ward
BUGS
The luminance value is used for comparison of pixels, although in certain anomolous cases (ie. highly saturated colors) it is possible that
pextrem will not pick the absolute minimum or maximum luminance value. This is because a fast integer-space comparison is used. A more
reliable floating-point comparison would be slower by an order of magnitude.
