Stay in the loop…

Follow the Tweets.

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.

Filtering IP address from ifconfig usefule in scripts

A method for aquiring the ip address using zsh. If you prefer the use of iproute2 (which, frankly, you should) then the following should provide the same (ip outputs CIDR addresses):

print ${$(ip -o -4 a s eth0)[4]}

we could also pass a qualifier to take only the IP and not the (CIDR) mask

print ${$(ip -o -4 a s eth0)[4]:h}

or, similarly, for the MAC address:

print ${$(ip l l eth0)[15]}

Useful in scripts while you just need an IP address in a variable.
