AWK is one of the most common UNIX tools to process text-based data in either files or datastreams. Written by Alfred Aho, Peter Weinberger, and Brian Kernighan, AWK "extensively uses the string datatype, associative arrays (that is, arrays indexed by key strings), and regular expressions." ComputerWorld interviewed Alfred Aho.

First, thanks for the nice AWK tips there. I should learn more AWK.
I'm still using only cut, sed, tr, etc.... I'm working mostly on Windows (which I do not like much) but that's my job - so cygwin on the help.
As for your example for cut and white spaces, here is how it can be solved:
cut --help | sed -r "s/[ ]+/ /g" | cut "-d " -f 2-
I guess sed can be used to replace two or more spaces to one, and then preprocess...
