#file1.rb
puts Dir.pwd # /tmp
require 'directory1/file2.rb'


#file2.rb
puts Dir.pwd # /tmp

Dir.chdir(File.dirname(__FILE__)) do
puts Dir.pwd # /tmp/directory1
end

puts Dir.pwd # /tmp

(But note that Dir.chdir with a block is not threadsafe.)

Hi,

The current directory (which is returned from Dir.pwd) is something
different from the directory where the program are stored. What about
__FILE__ pseudo constant that shows the file name of the loading
program?

matz.

I litle bit feel shame to admit it, but your suggestion is the shortest
solution.
Why I can't find this __FILE__ in all the tutorial that i read before I
submit to this mailling list
__FILE__ is the exactly what I want
