FWIW, I found the following a little awkward, given that these
are instructions for a Ruby application:

Note to Linux users: You can modify the necessary files with GNU sed
from the rails/ directory with the following command:

$ sed -i '/^#!/{s,local/,,}' public/dispatch.{cgi,fcgi,rb}

I.e., why isn't this a ruby command instead of sed?

That's the wonderful power of the wikis. You perceive this as a bug and
with the Edit link at the bottom of the page, you have the power to
change it! So I expect to see a new revision of that page edited by Bil
Kleb shortly ;)

P.S.: Thanks for the good talks in Virginia. Let's work something out
that can get your team out of the Cold Fusion dark and into the Ruby on
Rails light ;)

I would, but let the truth be known: My command-line ruby is so poor that
my sed equivalent is too Perl:

ruby -pi -e \$_.sub\!\(/^\(#\!.*\)local\\\//,\'\\\1\'\) public/dispatch.{rb,cgi,fcgi}

due to trouble with getting '\1' inside the argument to -e when using bash.

The following is cleaner but does not follow the sed command's behavior
and is still too Perlish for my tastes:

ruby -pi -e '$_.sub!(/local\//,"") if $_=~/^#!/' public/dispatch.{rb,cgi,fcgi}

Anyone?

How about:

ruby -pi -e '~/^#!/&&$_[/local\//]=""' files
