sed search and replace recursively

Shell Programming and Scripting
1

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!

What are you having trouble with?

If the sed script works with one file, it will work with all of them.

Write a script that works on a single file and call it with:

find . -type f -name '*.txt' -exec your_script {} \;
