Hi,

Silly question, maybe, but is there a simple command to query the

ip address? Something similar to 'hostname' for finding the computer's 
hostname.
I need the four dot-separated ip numbers.

I can analyze the output of 'ifconfig', but isn't there an easier way.

Thanks,

If reading the output of ifconfig is really too much trouble for you, 
then I would suggest writing up a small script or alias to grep the 
output of ifconfig.

A computer often has a number of associated ip addreses; so it is a bit
difficult. However interfaces usually have a unique address (or at least a prime
address) so it makes more sense to think in terms of the ip address of a 
particular NIC in the machine.

So ifconfig is the most reasonable way to find what ip addresses are 
associated with your computer.

For the sake of looking for a command that might do this, i whipped up 
this long one-liner:

ifconfig | perl -nle 'print $1 if(/(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})/)'

note that this will print the first ip address it finds of each line 
seperated by a newline, so be prepared to handle more than one.
