Show local/public IP adresses with or without interface argument using a shell function for Linux and MacOsX

Like the tiltle said, you can use an argument too ( the interface )

MyIps eth0

will show only the IP of this interface and the public IP

( tested with Linux )

You can add that function in ~/.bashrc, then

. ~/.bashrc

Now you are ready to call this function in all your terms...

Alternatives

What others think

This works on OS X (unlike almost all the other IP address commands that use ifconfig here) with the following changes: 1) change 'inet addr:' to 'inet ' and 2) ifconfig uses 'enX' rather than 'ethX' on linux.

So the command would be:

echo -e "local:\n$(ifconfig en0 | grep -oP 'inet \K(\d{1,3}\.){3}\d{1,3}')\n\npublic:\n$(curl -s sputnick-area.net/ip)";

to check the first ethernet IP address.

Ok, thanks for your contribution. Here is the good one, for both MacOsX and Linux :

ifconfig $1 | grep -oP 'inet (addr:)?\K(\d{1,3}\.){3}\d{1,3}' 1 is an optionnal interface. That must works with or without.

So in complete :

MyIps(){ echo -e "local:\n$(ifconfig $1 | grep -oP 'inet (addr:)?\K(\d{1,3}\.){3}\d{1,3}')\n\npublic:\n$(curl -s sputnick-area.net/ip)"; }
