to find min and max value for each column!
Hello Experts,
I have got a txt files which has multiple columns, I want to get the max, min and diff (max-min) for each column in the same txt file. Example:

cat file.txt
Code:
a 1 4
b 2 5
c 3 6

I want ouput like:
cat file.txt
Code:
a 1 4
b 2 5
c 3 6
Max 3 6
Min 1 4
Diff 2 2

Code:
awk 'min=="" || $2 < min {min=$2} END{print min}' file.txt

this awk command can find min from 2 column, but i have to change the column number, is there a one liner which can give me desired output in the same text file.
Thanks in advance.

DESCRIPTION

       Looks up a service zone by country in the "usps" table, then looks in the appropriate rate table for a price by that zone.

       Can aggregate shipments greater than 70 pounds by assuming you will ship multiple 70-pound packages (plus one package with the remainder).
