I have lines of text such as the following:

23,45,45,
24.45.65

I want to match "periods" not the "commas". I know that I can simply
[^\,] take the compliment of the commas for the above text, but assume
that's not sufficient. How can I match a period and only a period.
When I use

^[0-9]{2}\.

it matches both of the above lines. It matches 23, and 24..

(FYI: I'm using regexp in the context of egrep)
