Top Forums Shell Programming and Scripting Count number of unique values in each column of array Post 303011190 by Don Cragun on Monday 15th of January 2018 12:08:00 AM

Given the code suggested by Chubler_XL and Yoda, it is hard to imagine that anything is different in the way counts are accumulated for column numbers that are multiples of 13.

Can you provide us with sample data that demonstrates the inaccurate counts that you have reported?

What operating system (including release number) are you using?

Which version of awk are you using?
