Question

I have an email field that may be formatted in a few different ways.

1. [e-mail]

2. "hello world" <[e-mail]>

3. hello world <[e-mail]>

I would like to capture both the hello world string (if it’s there) and the email address (if it’s there). I have a regular expression that almost works, but it doesn’t quite.

sed -r  's/"?([^"]+)*"?\s<?([^>]+@[^>]+)>?/["\1","\2"]/' <<< 'Hello World <[e-mail]>'

Please help?

Update:

This should do what you want:

^(?:"?([^@"]+)"?\s)?<?([^>]+@[^>]+)>?$

This will store the first part, if there is one, into the first capturing group and the email address int o the second group.
