- I want to match standard email syntax (lowercased English, numbers and perhaps also some hyphens and underscores) with regex for a `sed` operation that matches and changes a single email address inside a file.
- The following code failed:
- read new_email_address
sed -i 's/^[a-zA-Z0-9-_]*$@^[a-zA-Z0-9-_]*$.^[a-z]*$/"${new_email_address}"/g' FILE- I know its problematic in the sense that files can have two or more email addresses and a global change is dangerous, but this is primarily just for learning and practice regex and `sed`.
