Hi, I am a beginner in Perl and have a very trivial query. I have some .expect files in my directory structure which are spread all throughout. I want to convert these files (only expect files) to .expect.bak. Please let me know as to how this can be done using Perl script. Even pointers to shell scripting will help.
