If PowerShell offers a simpler way to do something, do it For example, to find the IPv4 address on all network adapters on a local computer, run a single line. Since all proposed solutions seem to have circumstances where they fail, check for possible edge cases - no eth, multiple eth's & lo's, when would 'hostname -i' fail. If you want to use PowerShell to get the IP address in a simple script, by all means, use these cmdlets. So to get IP you need to find the IP after src, using awk, sed or grep ip route get 8.8.8.8 | awk -F"src " 'NR=1' )" With newer version of Linux you get more information with a typical output some like this: ip route get 8.8.8.8Ĩ.8.8.8 via 10.36.15.1 dev ens160 src 10.36.15.1 To find what IP adders is used connected to internet, we can use the ip route command. If the goal is to find the IP address connected in direction of internet, then this should be a good solution.Įdit 2021: Added "sed" and "grep" versions and new "awk" versions (some are gnu) If anyone would be interested in it just pm me. I know about grep and sed but I am not really good with them.Įdit: Firstly to say thank you for helping me with this problem, now I know much more. I'm currently playing around with the bash pipe and the awk command. The query I'm running looks like this: lab-1:/var/ dig +answer +short 10.11.11.11 I'd like to be able to get just the IP address returned.
#Bash script to get ip address how to#
Is there any command that allow me to do such a thing, to search in stream for informations I want to get?. As part of an installation script, I want to make an 'educated guess' about the machines public IP address. On Alpine Linux, I'd like to know how to extract just the IP address from a DNS / dig query. I want to display only the IP address in line: echo "Your IP address is: (IP_ADDRESS )".

I want to make big script on my Debian 7.3 ( something like translated and much more new user friendly enviroment ).
