Hi All,

I have posted the same code b4, but could not find my original post,
however this is a different question.  I am a newb, so here I go.
Thank you!


This is my error:

$ ruby test.rb
test.rb:46: undefined method `flock' for main:Object (NoMethodError)
        from test.rb:45:in `open'
        from test.rb:45
        from test.rb:42:in `each'
        from test.rb:42

Here is my code:

#!/usr/bin/ruby -w

require 'ftools'
array1 = Dir.glob("*.log")
if ( array1.length >= 1 )
    array1.each { |file|
        File.copy(file, "#{file}.orig")
        if (File.size?(file) > FSIZE)
            File.open(file, 'r+') do |f|
                flock(f, File::LOCK_SH) do |f|
                f << "i got a lock"
                end
            end
        end
    }
else
    raise StandardError, "Array 'array1' has no values, logs will not be
rolled!"
end
