getting own ip address
Can someone tell me what is the best way to get your ip address through a command line command.
cat /etc/hosts | grep `hostname` | awk '{print $1}'
gives 2 ip.
127.0.0.1 and actual ip address
while ifconfig -a gives a lot of information and its difficult to get ip address in between.
Is there is any direct command?

hostid(1) General Commands Manual hostid(1)
NAME
hostid - Sets or displays the identifier of the local host
SYNOPSIS
/usr/sbin/hostid [hostname | hexadecimal_number | internet_address]
DESCRIPTION
The hostid command displays the 32-bit identifier of the host as a hexadecimal number in host standard byte order. The identifier must be
unique across all hosts and is commonly set to the Internet address of the specified host. The superuser can set the host ID by specifying
a hostname, internet_address, or hexadecimal_number argument. The identifier is stored in network standard byte order.
EXAMPLES
To display the identifier of the local host, enter: $ hostid
0xc009c803
The hostid command displays the identifier of the host as a hexadecimal number in host standard byte order. To set the identifier
of the local host to the local Internet address, enter: $ hostid 555.5.55.555
The hostid command converts the Internet address to its hexadecimal equivalent, and then sets the local host to this address.
Note that the sample Internet address in this example, 555.5.55.555, is not a valid Internet address and would cause hostid to
return an error.
