Which is the shortest way to get the variable $DISTRIB_CODENAME from /etc/lsb-release?

I want to make this somewhat shorter:

$ sudo add-apt-repository \
  "deb http://some-repo/ubuntu $(grep CODENAME lsb-release |sed s/^.*=//g) main"

You can source that file in bash (or any Bourne-like shell) to set them as shell variables:

source /etc/lsb-release
sudo add-apt-repository "deb http://some-repo/ubuntu $DISTRIB_CODENAME main"

The command lsb-release has an option to display codename according to the distribution release:

apt-get install lsb-release
lsb_release -c -s

So you can try to rewrite it like this:

sudo add-apt-repository "deb http://some-repo/ubuntu $(lsb_release -c -s) main"

For details, check man lsb_release.
