Finding LocalHost IP Address

I am writing a program that need to be run on several machines. I am running UNIX and wanted to know if there is a command similar to ipconfig (in DOS) that would return the IP Address of the machine that I am working on. (Not just the loopback address of 127.0.0.1).

To do so, set the i] variable of interface i with in Options are: Print debugging information. Use ethernet encapsulation only. Use SNAP encapsulation only. Transmits count requests and waits for each one to time out before giving up. interface_name Identifies the interface to request information about. If a response is received, it prints the IP address to its standard output. This information can be used to configure the interface as seen in If a response is not received, the client will retransmit after 2 seconds, and then after 4 seconds. After that, retransmissions occur every 8 seconds. RETURN VALUE
Exit status is 1 if the command fails or no RARP response is received. Exit status is 0 and the IP address is printed to standard output if a response is received. LIMITATIONS
