git-current-branch

Allow to setup a bash to display current git branch of working repository.

So first,lets put these two files to your home dir:

.git-prompt.sh 
.git-completion.bash 

Set permissions

$sudo chmod +x .git-prompt.sh 
$sudo chmod +x .git-completion.bash

Then edit your .bashrc file

$vi ~/.bashrc

And put to end of file:

 if [ -f ~/.git-completion.bash ]; then
    source ~/.git-completion.bash
    source ~/.git-prompt.sh
    export PS1='[\u@\h \W]$(__git_ps1 "(%s)")\$ '
fi

Then when you will navigate to some git repository you will see something like

[user@host project](master)$
