Say I have this
str="System IP is 9.9.9.9 on port 3442"
str2="ip 192.168.0.9 is using port 222"
I would like to remove all substrings except for the one which contains periods which would leave me with :
9.9.9.9
192.168.0.9
Any ideas ?

1Its duplicate question, you can use `grep -oE '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}'` to get the IP substring from the main string – P.... May 28 '19 at 20:59
