Hi,
I'm new to Ruby. I'm trying to scan an array for lines that match the
following format:
<string> <integer>
Example:
IN:
fred.smith 1970
sarah 1980
dr cooper
OUT:
fred.smith 1970
sarah 1980
any tips are appreciated, thanks.

Are you new to programming and regular expressions in general?
Those examples are pretty basic; what have you tried so far?

You could do that with grep if you wanted to.
Put together a regex for a string of characters followed by whitespace followed by digits.
Since it looks like a homework question, I'm just giving you general guidance.
Also, at the last Lone Star Ruby Conference, Nell Shamrell did a talk on regular epressions. I think the video is online. It's a good place to start.

It's not what I know that counts.
It's what I can remember in time to use.

match is a method on regular expressions, so /^\w+\s\d+$/.match(text) would be the right syntax
I don't think "." will be matched by \w, so you may need to use a match for non-whitespace characters.
If I was writing it, I would allow for multiple whitespace characters as dividers and accept trailing whitespace (just because it's easy to have by accident).
