Question

I am trying to extract some data from URLs in a LOG file and I’m almost there but the last part I am stuck on.

Here is the regex I have come up with so far,

(\?.*\s+)

Example of URLs I am working with

json?userId=1234&email=[e-mail] HTTP/1.1

And I want to pull out

userId=1234&email=[e-mail]

Across multiple lines of similar URL lines. The regex above gets the right stuff at the start but does not stop after the whitespace. What am I missing to make it not include the ? and end at the white space properly?

Edit: Clarified question a bit.

Answer 1

This works in sed.

echo “json?userId=1234&email=[e-mail] HTTP/1.1” | sed ‘s/.*?\(.*\)\s.*$/\1/

you might also try.
(\?[^\s]+)
match as many not space characters after a ?
