sorry but the fun to produce oneliners is something i cannot resist..

I ended with a wonderful (;=)) one if you accept to pass range à la Perl 1,2,4..5 instead of hyphenated ones like 1,2,4-5

I'm very proud of the solution to workaround the off by one error between line number (from 1) and array elements (from zero): a two char fix 0, was enough.

For the joy of many, another evil use of eval (warning: win32 doublequotes!)




      perl -e "BEGIN{$w=pop @ARGV}print +(0,<ARGV>)[eval $w]" linenumb
+er.txt 1,3..5

PS even simpler: 

      perl -e "print +(0,<ARGV>)[eval pop]" linenumber.txt 1,3..5

There are no rules, there are no thumbs..
