Proste pytanie, jakim poleceniem, czy to cut czy awk wyszukać w stringu (linijce tekstu) wszystkie czterocyfrowe liczby? Z góry dzięki za pomoc!

Nie lepiej grep?

grep -o '[0-9]\{4\}' plik.txt

a to nie znajdzie fragmentu liczby pięciocyfrowej?
coś w stylu:

grep -o -P '\b\pN{4}\b'

btw. backslash przed klamrą jest niepotrzebny.
