PS1 var-->

Show IP Address in prompt --> PS1 var

export PS1="[\u@`hostname -I` \W]$ "
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

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?
