Automatically delete branches from git repository using terminal

On this video I will explain you how you can easily erase your git branches on an automated way
using a very useful set of commands from your Linux or Mac terminal, so let´s go to it.

The first thing we need to do is be able to get the list of branches currently available on our local repository.
For this you can do the "git branch -l" command. This will list us the branches available. You will see that we have set up
4 branches on our test repository.

From here we will introduce the power of the terminal using a pipeline, we will pipe the list of branches to the grep command which is very useful
to match patterns in general and for this case we will use the -v option wich stands for "Invert match", along with this option we will be using the -e
option, this will enable the ability to use a regular expression, In this case I will be using a regular expression to skip the master and the dev branch since I am using the "invert" option so now on the new list I only see 2 branches, so now I only need to find a way to use them as a source to delete them which is what I really need. In order to delete them we need to pass them as arguments to the delete command in git, for this we can use the xargs command, xargs allows you to use a list coming from a pipe to be passed to the next command.

So along with the xargs command you can proceed with the "git branch -d" , this command what it does is deleting the branches that has been merge from your local repository, If we execute this we will see that we deleted the branches. Just as the "-d" we have the uppercase "-D" that deletes also the branches that are not merge yet too. So with this combination you can actually get new ways to clean your git repository.
