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.

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.

Hi folks,
Here i have written a shell script to calculate a maximum number from 10 numbers entered on command line.
max=0
echo Enter 10 numbers , one at a time
for i in 1 2 3 4 5 6 7 8 9 10
do
read n
max=`expr $max + $n`

This might be a simple answer but I can't for my life figure it out. If I input "bat", how do I get the condition to pick it up with the wild card *at*.
#!/bin/bash
read -p "enter" BOO
if ; then
echo "you win"
else
echo "you lose"

Hi :o
I'm working on Windows, with gawk,
and let's say I have two files to compare.
searching for a script to do a text comparison I came across to this line:
gawk "{if(NR==FNR){A}else{B}}END{for(x in A){if(!(x in B))print x>\"1not2.txt\"}for(x in B){if(!(x in A))print x>\"2not1.txt\"}}"... (7 Replies)
