Bug sed search and replace recursively
Hi,

I tried making a shell script which recursively search in a given directory for all files *.txt and then search and replace some text and after that
save each file as $filename.dynamips.txt

I would like to get this done with sed. I tried but couldn't get it to work.
BTW this is not homework. It is just a bunch of lab files I want to convert for using with dynamips

Thanks!
