ipconfig
 

I want to see all my ip address info...I'm new to linux and tried using "ipconfig" command, I'd read that was supposed to work, did not...

it's ifconfig
ipconfig is for windows

thanks, I tried using "ifconfig" command in both user and superuser mode, but "command not found" both times.....

Maybe your path is messed up. Try:

/sbin/ifconfig

and if that doesn't work, try searching for it with find or locate.
