BASH extract ip addresses with grep
ifconfig list you ip configurations and pipes it to grep. From grep I used a regular expression to extract the data.
Code: ifconfig | grep -Eo '\b[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}\b'output example 127.0.0.1 192.168.2.1 192.168.2.255 169.254.254.87 169.254.255.255 10.59.0.214 10.59.3.255 10.211.55.2 10.211.55.255 10.37.129.2 10.37.129.255 192.168.170.1 192.168.170.255 192.168.97.1 192.168.97.255 |

RE: BASH extract ip addresses with grep
Interesting way of getting IP-s, in Windows Batch File you can do it with "netstat -n" and it lists you !

RE: BASH extract ip addresses with grep
yea but it doesn't just pull the ips out of each line. ipconfig list the ips too
 . This command removes all other text but ips from a line if found
