I have a file, which holds phone number data, and also some useless stuff.
I'm trying to parse the numbers out, and when there is only 1 phone number / line, it's not problem.
But when I have multiple numbers, sed matches the last one (even though everywhere it says it should match only match the first pattern?), and I can't get other numbers out..
bla bla bla NUM:09011111111 bla bla bla bla NUM:08022222222 bla bla bla
When I parse for the data, my idea was first to remove all the "initial" "bla bla bla" in front of the first phone number (so I search for first occurrence of 'NUM:'), then I remove all the stuff after phone number, and get the number.
After that I want to parse the next occurrence from the leftover string.
So now when I try to sed it, I always get the last number on the line:
>sed 's/.*NUM://' data.txt 08022222222 bla bla bla >
Primarily I would like to understand what's wrong with my understanding of SED. Of course more efficient suggestions are welcome!
Doesn't my sed command say, replace all stuff before 'NUM:' with '' (empty)? Why it matches always the last occurrence ?
