I wrote my own log rotator...for reasons...

logrotate.rb

#!/usr/bin/ruby

require "fileutils"

ROTATE  = ENV.fetch("ROTATE", 52).to_i
VERBOSE = ENV.fetch("VERBOSE", "false") == "true"
file    = ARGV[0]

puts "Rotating #{file}..." if VERBOSE

current_time = Time.now.to_f.to_s
new_file     = "#{File.dirname(file)}/#{File.basename(file)}.#{current_time}#{File.extname(file)}"

puts "To #{new_file}..." if VERBOSE

FileUtils.copy(file, new_file)
puts "Copied." if VERBOSE
File.open(file, "w+") { |f| f.truncate(0) }
puts "Truncated." if VERBOSE

pattern   = "#{File.dirname(file)}/#{File.basename(file)}.*#{File.extname(file)}"
all_files = Dir[pattern].sort

exit 0 unless all_files.size > ROTATE

puts "More than #{ROTATE}..." if VERBOSE
first      = all_files.take(ROTATE)
left_overs = all_files - first

puts "rm'ing #{left_overs.size} files..." if VERBOSE
left_overs.each { |j| FileUtils.rm(j) }
puts "Done."
