Subject: A couple of basic questions

Hi,

Q.1: I was processing file/dir names with the following snippet:

Find.find(wd) do |item| # Subordinate file/directory fully-qualified
names
  if File.directory?(item)
    # Process directory name
    if item =~ /portfolio/i
      item_saved = '  ' + item
      item.gsub!(/portfolio/, 'position')

When I saved item in item_saved without modification,  the gsub change
both the item name as well as the saved name (because what was saved
was a reference to item, not item's content).  So my work-around was
to save a modified name. That doesn't seem like "The Ruby Way".
What's a better way?

Q. 2:  In that same snippet,  I made two substitutions:

      item.gsub!(/portfolio/, 'position')
      item.gsub!(/Portfolio/, 'Position')

That's also a kluge.  But the following didn't compile:

      item.gsub!(/([pP])ortfolio/, $1 + 'osition')

Is there a "Ruby Way" to reduce the redundancy?

Thanks in Advance,
Richard
