Question

Yep – another noob regex query, which I can’t seem to get.

I’m trying to get all matches for the string foo.mydomain.com/ or foo.mydomain.com:1234/ or foo.mydomain.com:<random port>/ but any other paths do not match, ie. foo.mydomain.com/bar or foo.mydomain.com/bar/pewpew

I tried to use: foo.mydomain.com(.*)/$
(which starts with anything, then foo.mydomain.com, then any thing after that until a slash, then end. (This search query is anchored to the end of the line.)

But that doesn’t work. It doesn’t match when I pass in foo.mydomain.com:1234 but it correct says foo.mydomain.com/bar/pewpew is not a match (as expected).

Try:

^foo\.mydomain\.com(?::\d+)?/?$

• ^ : Start anchor
• \. : . is a meta char..to match a
  literal . you need to escape it with \
• (?:) : grouping
• \d : A single digit
• \d+ : one or more digits
• ? : makes the previous pattern optional
• $ : End anchor
