Can't use fileutils

ruby-talk
1

Hi out there,

I'd like to use "FileUtils*", but ruby does not agree:

irb(main):003:0> FileUtils.mkdir('uno')
NameError: uninitialized constant FileUtils
        from (irb):3
irb(main):004:0>

But the file ist allreay in the lib:
ram@lilith:~/src/tar$locate fileutils.rb
/usr/local/lib/ruby/1.8/fileutils.rb

Dir works:
irb(main):001:0> Dir.mkdir('uno')
Errno::EEXIST: File exists - uno
        from (irb):1:in `mkdir'
        from (irb):1

I use ruby rby 1.8.2.

Where's my mistake?

regards

You have to "require 'fileutils'" before using its methods.

Thanks Hynek,
of course this fixes the problem.
I'm not that certain about using inernal and external things yet.
