Show your branch name on the Linux prompt, changing .bashrc on Ubuntu 16.04.

.bashrc

Show your branch name on the Linux prompt. Updated
  
  1-Go to ~/ directory, or /home/"username";
  2-type sudo subl .bashrc. So this will be the full command ila@ig:~$ sudo subl .bashrc. That will open the .bashrc file
  3-After this Introductory sentence of the .bashrc:
    # ~/.bashrc: executed by bash(1) for non-login shells.
    # see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
    # for examples
  4-Put this function declaration:
    # Add git branch if its present to PS1
    parse_git_branch() {
      git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1)/'
    }
  5-Find this portion of the code:  
      if [ "$color_prompt" = yes ]; then
         PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
      else
         PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
      fi
      unset color_prompt force_color_prompt
  6-And change for this:
    if [ "$color_prompt" = yes ]; then
       #PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ ' #Igor put in comment
       PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[01;31m\]$(parse_git_branch)\[\033[00m\]\$ ' #Igor added this line
    else
       #PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ ' #Igor put in comment
       PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w$(parse_git_branch)\$ ' #Igor added this line
    fi
    unset color_prompt force_color_prompt  
    
    7-GO to the master directory, make a `$git add .` and  `$git commit -m "The first commit"` IF IT WAS NOT DONE BEFORE. 
      THE SHELL WILL BE ABLE TO SEE THE BRANCH NAME JUST AFTER THE FIRST COMMIT WAS DONE.
  
  At the end of this process you will have a colored shell with the git branch name.

  3-Usar o seguinte codigo dentro do `.bash_profile`
  
  `
  parse_git_branch() {
  git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1)/'
}

PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[01;31m\]$(parse_git_branch)\[\033[00m\]\$ '

OLD .bash_profile that is working:

parse_git_branch() {
  git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1)/'
}
