Subject: Re: how to sort this array

here is my code:

C:\Users\Alex>irb
irb(main):001:0>  files=[
irb(main):002:1*    "c:/ruby/self/2004/20.txt",
irb(main):003:1*    "c:/ruby/self/2004/3.txt",
irb(main):004:1*    "c:/ruby/self/2004/2.txt",
irb(main):005:1*    "c:/ruby/self/2004/10.txt",
irb(main):006:1*    "c:/ruby/self/2004/1.txt"
irb(main):007:1> ]
=> ["c:/ruby/self/2004/20.txt", "c:/ruby/self/2004/3.txt", 
"c:/ruby/self/2004/2.txt", "c:/ruby/self/
2004/10.txt", "c:/ruby/self/2004/1.txt"]
irb(main):008:0>
irb(main):009:0*
irb(main):010:0* files=files.sort_by do|s|
irb(main):011:1* s.split(/\//)[-1].split(/\./)[0].to_i
irb(main):012:1> end
=> ["c:/ruby/self/2004/1.txt", "c:/ruby/self/2004/2.txt", 
"c:/ruby/self/2004/3.txt", "c:/ruby/self/2
004/10.txt", "c:/ruby/self/2004/20.txt"]
irb(main):013:0>

I am not sure if it is the Rubyish way.
