Rails - Aug 2005 - Gotcha in deploying Windows-edited files to Linux/lighttpd

I''m developing a Rails app on my WinXP server. When I tried to deploy
it to a linux server, lighttpd started complaining about ":bad
interpreter:"  It took me some digging before I found the culprits, so
just posting here to spare others a little time.

The culprit is the dispatch.* file in /public. Obviously, the she-bang
command needs to be modified to the linux equivalent. Less obvious was
the /r/n to /n conversion needed.

This did the trick:
perl -i.win -npe ''s/\r\n/\n/g'' dispatch.*

It renames the original files to dispatch.*.win and strips the
characters that cause lighttpd to balk.

Another option for the \r\n to \n conversion are the dos2unix and
unix2dos commands. They work quite well in most situations.
