A couple of points to mention. 1) You can use $PROGRAM_NAME instead  
of $0, it's
a little more readable. 2) Make sure you have not done a Dir.chdir  
before the File.expand_path

% cat path.rb
puts $PROGRAM_NAME
puts File.expand_path($PROGRAM_NAME)
Dir.chdir "pdf"
puts File.expand_path($PROGRAM_NAME)

% ruby path.rb
path.rb
/Users/jdf/projects/devel/ruby_test_code/path.rb
/Users/jdf/projects/devel/ruby_test_code/pdf/path.rb
