Extract specific strings from file

Question

Good morning guys, I'm trying to extract from this file

I have necessary extract only alls links with pattern '/9.4.10/':

grep "/9.4.10/" test.txt

After this command i have see all links

How can I solve this problem?

grep returns a matching line. In your file you have 14 lines according to cat test.txt | wc -l , so grep is not the tool you want, as one matching will return the whole huge line. — samthegolden

Maybe help to pull out all the links, and then grep.

Try it:

cat test.txt | grep -Eo "(http|https)://[\da-z./?A-Z0-9\D=_-]*" | grep "\/9.4.10\/"
