Hi shakersort,
If you want to know the IP address of the machine that you are using, run

Quote:

$ /sbin/ifconfig

You can also use "ip addr" . The command is ip soif its not in your path try /bin/ip addr
or /sbin/ip addr

anc@orac:~> /bin/ip addr
1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
link/ether 00:0e:a6:8c:f3:16 brd ff:ff:ff:ff:ff:ff
inet 192.168.254.197/24 brd 192.168.254.255 scope global eth0
inet6 fe80::20e:a6ff:fe8c:f316/64 scope link
valid_lft forever preferred_lft forever
3: sit0: <NOARP> mtu 1480 qdisc noop
link/sit 0.0.0.0 brd 0.0.0.0

You can spell it out instead of abbreviating too. So to find your ip address at the command line you type ip address at the command line. Damn that's just too easy! Why can't Windows be so simple? LOL

[climber@blackhole ~]$ ip address

Actually, the latest versions of iproute2 do not accept `ip addr' anymore. You must use `ip address' (or patch the source yourself). I'm not sure whose idea it was to change this (or even if s/he realized the consequences), and I don't have time to find out.

If you just want the IP address of eth0 and nothing else (for example to use in a variable or script) you can use this:

Code:

ifconfig eth0 | grep "inet addr:" | awk -F: {'print $2'} | cut -d\  -f 1

You'll probably have to use the full path to ifconfig if you're not root.

Thanks for that - I have to admit I didn't pay attention to the forum it was in, just saw it in a listing of new posts...
