Hello again Mohamed!

Now I understand you better. To answer your question, We'll use this example:

echo fooosomethingbarrrrr | awk '{ match($0, /(fo+).+(bar*)/, arr)}END{print arr[1] arr[2]}'

And here's the result!

fooo barrrrr

Now As you can see, match take as arguments a given string, a regex, and an array in which it returns the different groups.

Please keep in mind that match with 3 arguments i s only available for gawk and not mawk.

Hope this answers your question!
