Because your wheel will not work on i.e. Windows without the "tail" 
binary, but the ruby wheel will work wherever ruby works. And I honestly 
think that everything that is possible in ruby, should be done as well.
The whole modularity of Unix tools has also led to shell scripts, which 
are just plain UGLY and a mess to maintain, especially the more 
complicated they grow (which is only less true for ruby scripts, because 
maintaining even complicated ruby scripts is a lot easier IMHO)

I personally would rather maintain a collection of ruby or python files, 
than countless shell scripts that use various tools with various 
different syntax rules (awk, sed, grep and so on) to cope with.

Noone will use a wooden wheel to drive on the 24 Hours of Le Mans.

Use the better wheel.

Use Ruby.
