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.

bash only - no grep, sed, awk, whatever - zero overhead

alternatively using ifconfig instead of "ip addr ..."

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 :)

ip addr show dev eth0 | awk '/inet/ {sub(/\//, " "); print $2}'

No grep or sed overload, just pure awk.
