How to check my IP in Linux?

I have a text based Linux server - how do I check my IP?

I tried using "ifconfig" but received a 'command not found' error.

/sbin/ifconfig

Often, people add /sbin:/usr/sbin to their path to pick these things up.

ifconfig generally works even if you aren't root. It's just not in the default PATH, so you have to type /sbin/ifconfig

You can try typing 'ip address show' (or '/sbin/ip address show')  as well. This is a newer syntax not available on all machines. ifconfig should work everywhere.

There are a great family of very simple but very useful scripts that, in Debian at least, come packaged with the 'ipmasq' package (and should be separated from it into a new package, IMHO, due to their usefulness). The one relevant to what you want is called 'ipofif', and is simply

#!/bin/sh
#
# ipofif        Determines the IP address of the interface given on the
#              commandline

# v1.2  10 Feb 2001

/sbin/ifconfig $1 | grep 'inet addr:' | sed 's/.*inet addr:\([0-9.]*\).*/\1/g'

You know you've been reading GrokLaw too long when you parse the "IP" in the title as "Intellectual Property"
