Regexp challenge

[Casimir Pohjanraito]

Just out of curiosity, for fun:

Whats the rubyest ruby program you can code for opening a directory of
files and replacing a particular string in all files (if found) with
another string?

Lets suppose that all files in directory are text and the string to search
for is "target", and replace string is "practice".

From inside the directory in question:

$ ruby -pi -e 'gsub("target", "practice")' *

<laughs> I come from Perl where tricks like that our very common,
which is probably just proof that my solution fails "the rubyest
ruby" requirement of the question.

Well, you did fail to use a regular expression

Well, I was tempted to comment that your solution seemed more perlish
than rubyish, but it was against my better nature. <G>
