commandlinefu.com is the place to record those command-line gems that you return to again and again.
Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.
You can sign-in using OpenID credentials, or register a traditional username and password.
First-time OpenID users will be automatically assigned a username which can be changed after signing in.
Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.
Use your favourite RSS aggregator to stay in touch with the latest commands. There are feeds mirroring the 3 Twitter streams as well as for virtually every other subset (users, tags, functions,…):

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:
For machines that have many ip blocks spanning different Class C's, this will show which ones.
not shown ifconfig error
Gives the DNS listed IP for the host you're on... or replace `hostname` with any other host
Thx Mass1 for the sharing
Print the IP address and the Mac address in the same line
Is the better option on a Open SuSE Box
On wired connections set 'eth0' instead of 'wlan0'
Returns the IP, broadcast, and subnet mask of your interfaces absent any other extraneous info.
I know it's a bit lame, but I've created an alias for this when I *quickly* want to know what a system's IP is. Small amounts of time add up :)
Command is properly working on HP-UX 11.31
Why use grep and awk?
Shows the interface and the ip-address
This is what we use.
You can grep -v 127.0.0.1 if you wish.
This also works on non-Linux machines. If you have GNU sed you can do it more elegantly:
ifconfig | sed -n 's/^\s*inet \(addr:\)\?\([^\s]*\) .*/\2/;T;/^127\./d;p'
Shows only IP-addresses of ifconfig except 127.0.0.0/8.
I fixed the script to work on more systems and configs
/inet/!d; #grep inet
/127.0/d; # grep -v 127.0
/dr:\s/d; # grep -v dr:
s/^.*:\(.*\)B.*$/\1/ # remove everything exept between : and B
