Show IP Address in prompt --> PS1 var

when working with many machines in a computer lab need to know the IP addr is very large, this is a simplistic solution to make things easier


There are 2 alternatives - vote for the best!

Terminal - Alternatives
export PS1="[\u@`curl icanhazip.com` \W]$ "

Know a better way?

If you can do better, submit your command here.

What others think

The OSX hostname command doesn't have an -I flag

@hagbard23: yes, i have a mac, too. So I submitted same command, but for your internet IP + it works on MacOS X as well.

Or for your local IP:

export PS1="[\u@`ifconfig | grep "inet " | grep -v 127.0.0. | awk '{ print $2 }'` \W]$ "

The problem with this command, is it assumes you're running a specific hostname(1). Also, it doesn't account for multiple IP addresses, even though they will be space-separated. Lastly, it's using backticks, which are evil.

@peshay Ouch. awk(1) is a bit more powerful than you're willing to give credit to:

export PS1="[\u@$(ip a|awk '/g/{print$2}')]$ "

Gives the same result, although one IP per line. Much cleaner though, don't you think?
