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.

List your MACs address

Linux specific, requires iproute2 (but most distros have that by default now)

Alternatives

There are 5 alternatives - vote for the best!

Terminal - Alternatives
lsmac() { ifconfig -a | sed '/eth\|wl/!d;s/ Link.*HWaddr//' ; }
cat /sys/class/net/eth0/address
ifconfig eth0 | grep -o -E '([[:xdigit:]]{1,2}:){5}[[:xdigit:]]{1,2}'
for f in /sys/class/net/*; do echo -e "$(basename $f)\t$(cat $f/address)"; done

Requires sysfs mounted on /sys - may only be useful for Linux systems.

Could also use "printf '%-8s %s\n' $(basename $f) $(cat $f/address)" instead of echo.

cat /sys/class/net/*/address

No need for the ls -r and a sort is also not really needed.

Know a better way?

If you can do better, submit your command here.

What others think

awk can do the task you're performing with grep.

ip addr show eth0 | awk '/ether/{print $2}'
