Bash script to get all IP addresses

Question

I am trying to write a bash script to get all IP addresses on a server. The script should work on all major distros. Here is what I have:

ifconf         


        

Answer 1

Simply using hostname you can get a list of all your IP addresses, using the -I flag.

i.e.

$ hostname --all-ip-addresses || hostname -I
10.10.85.100 10.20.85.100 10.30.85.100

whereas

$ hostname --ip-address || hostname -i
::1%1 127.0.0.1
