If you use the fish shell its quite straight forward  fish is an interactive shell which comes with lots of goodies  You can install it using apt-get   sudo apt-get install fish   you can then change the prompt setting using   gt  fish config  Web config started at  http   localhost 8001    Hit enter to stop  Created new window in existing browser session    now go to http   localhost 8001  open the prompt tab and choose the classic   git option    Now click on the use prompt button and you are set

git 1 9 3 or later  use   git ps1  Git provides a shell script called git-prompt sh  which includes a function   git ps1 that     prints text to add to bash PS1 prompt  includes branch name    Its most basic usage is       git ps1  master    It also takes an optional format string       git ps1  git   s   git  master    How to Get It  First  copy the file to somewhere  e g     git-prompt sh    Option 1  use an existing copy on your filesystem   Example  Mac OS X 10 15      find   -name  git-prompt sh  -type f -print -quit 2 gt  dev null  Library Developer CommandLineTools usr share git-core git-prompt sh   Option 2  Pull the script from GitHub   Next  add the following line to your  bashrc  zshrc   source    git-prompt sh   Finally  change your PS1 to call   git ps1 as command-substitution   Bash    PS1    u  h  W    git ps1     s           Zsh   setopt PROMPT SUBST   PS1    n  m  c    git ps1     s           git  lt  1 9 3  But note that only git 1 9 3  May 2014  or later allows you to safely display that branch name     See commit 8976500 by Richard Hansen  richardhansen       Both bash and zsh subject the value of PS1 to parameter expansion  command substitution  and arithmetic expansion         Rather than include the raw  unescaped branch name in PS1 when running in two- or   three-argument mode  construct PS1 to reference a variable that holds the branch name         Because the shells do not recursively expand  this avoids arbitrary code execution by specially-crafted branch names such as       IFS   cmd sudo rm -rf    cmd      What devious mind would name a branch like that      Beside a Mom as in xkcd   More Examples  still dreaming 1 reports in the comments      This seems to work great if you want a color prompt with xterm  in my  bashrc      PS1     e 0  u  h   w a   n  debian chroot    debian chroot     033 01 32m   u  h   033 00m      03  3 01 34m   w   033 00m      git ps1            Everything is a different color  including the branch    In  in Linux Mint 17 3 Cinnamon 64-bit    PS1    debian chroot    debian chroot     033 01 32m   u  h   033 01 34m    w   033 00m      git ps1
