Subject: mtime.max

Hi All,

My goal is to get the oldest file using mtime.to_i then delete it.
However my
puts stats.to_a.max does not seem to print out the oldest mtime
data/file, rather its printing out the 2nd to oldest file;
prod_db_bkup_Tue2009-10-271455.gz

Correct me please and show me the code.

thx!

d=Date.today
t=Time.now
require 'enumerator'
    stats = Hash.new
    DB_BKUP1.each do |dbfile|
        stats[dbfile] = [File.stat(dbfile).mtime.to_i]
    end
    puts stats.to_a,"\n\n"
    puts stats.to_a.max
end
