Regexp challenge

Ruby

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”)’ *

Well, you did fail to use a regular expression :wink:

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