Feature Requests

[Marc Perkel]

I'd like to ask again (you liked the idea but I'm not seeing it 
implemented) that on the utilities head ad tail that the -c option be 
not only in bytes but also in k,m,g as in 10k 200m 2g ....

I have another request. In the utility uniq I'd like to see the switches 
--min --max to specify a range of number of uniques that will generate 
an output. For example:

--min=5

Mean that there has to be at least 5 of something before there's an output.

--max=10

Output if there is less than 10 matches.
