Hello,

I need regex help.

I have this url (for example)

I want to identify if the second folder contains 'en' (true or false)

How do I do that with regex?

Numerous

https?:\/\/[^/]+?\/[^/]{2}\/

https?:\/\/[^/]+?\/eu\/

path rx:\/[\w]{2}$

Solution 1

Try:

(?<=https?:\/\/.*?\/.*?\/)en(?=\/)

If the regex matches, the second folder is "en". If it doesn't, it isn't.

If you are going to work with regular expressions, then get a copy of Expresso[^] - it's free, and it examines and generates Regular expressions.

Assuming your using extended POSIX, you were very nearly there with the first example posted: The following seems to work for me:

https?:\/\/[^/]+?\/[^/]+/en/

If you want to capture the 2nd path element, then the following sed extended POSIX regex also works

sed -E -e "s/https?:\/\/[^/]+?\/[^/]+\/([^/]+)\/.*/\1/"
