What output do you want if all fields are zero?
I assume that you know that sed is not a common tool for this project, and, as you said, bash isn't well known for handling floating point values. If you want to process your file entirely in shell code, ksh would be a good choice. Otherwise, as you well know, awk is perfectly suited to problems like this.
What have you tried to solve this on your own? Where are you stuck?

It works well for most of the cases. However lets say diff is -0.17 and minm is -0.0017. In such a case the comparison seems to fail. Is the correct way to compare a mixture of positive and... (12 Replies)
