Nope. The block passed to find is not a filter. Find takes an argument as well 
as a block and it executes the block for every file it finds. Find always 
returns nil. So you can't call each on the return value of find and using it 
as the default value for inject makes no sense (as it's the same as 
inject(nil).
Find.find(src1).each do |file|
can be replaced with
Find.find(src1) do |file|

The inject could be replaced with:
src1 = []
Find.find(src) do |file|
  src1 << file unless $file_exception[i].any? do |x|
    /#{x}/i =~ File.basename(file)
  end
end

or:

require 'enumerator'
src1 = Find.enum_for(:find, src).reject do |file|
  $file_exception[i].any? do |x|
    /#{x}/i =~ File.basename(file)
  end
end
# (both untested)

HTH,
Sebastian
