IP address of current host

hostname -i
I've seen some versions of hostname that don't have the -i option, so this may not work everywhere. When available, it's a better alternative than using ifconfig and wasting eyeball muscle to search for the address, and it's definitely simpler than using awk/sed.

What Others Think

On my ubuntu system, returns which is less than useful. Trying host $(hostname) actually returns an IP though, but it fails on networks that use only IP's, and not dhcp client names

I don't know about the hard to find part, but you can always create a short alias with awk if finding an IP in ifconfig is that difficult for you.

The 'moreutils' package has another solution to this, and is available under the same name under debian/ubuntu. To ask for the network address of an interface, say ifutils -pN eth0 to get the ip address of eth0. Although this only gives the right answer for only one of my two interfaces with actual IP addresses. Another way is to use the 'ip' command from the 'iproute' package: ip addr show eth1 Or this hacky one in case you are behind a NAT to determine your external IP address: wget www.whatismyip.com/automation/n09230945.asp -O - -o /dev/null
