Couple typos:

"In the git-completion.bash file" should be "In the .git-completion.bash file"

"In the git-prompt.sh file" should be "In the .git-prompt.sh file"

Updating the permissions is not necessary.

Step 4 should also include adding

    source ~/.git-completion.bash
    source ~/.git-prompt.sh

Step 5 you can add "Run . ~/.bash_profile" or "close and re-launch your terminal"

Thanks for the tips!

That prompt can be really slow, as it runs `__git_ps1` multiple times (through several branches of the conditional, and then for the final output). On my git.git repository, running `time __git_ps1` takes about .085s. If I hit the "cyan" condition in the prompt, we run it three times, and doing `time eval "echo \"$PS1"\""` takes about 0.263s, which feels noticeably laggy.

Changing it to cache the result, like this:

   export PS1=$LIGHT_GRAY"\u@\h"'$(
    g=$(__git_ps1 " (%s)")
    if [[ "$g" =~ \*\)$ ]]
    then echo "'$YELLOW'$g"
    elif [[ "$g" =~ \+\)$ ]]
    then echo "'$MAGENTA'$g"
    else echo "'$CYAN'$g"
    fi)'$BLUE" \w"$GREEN": "

drops it back down to the .085s range.

I have a couple other suggestions:

1. Put your dotfiles in GitHub

2. Consider using zsh -- the completion is great, and it's easy to build a great prompt. I know prompts are personal taste, but I'm enjoying mine: https://github.com/hoov/dotfiles/blob/master/zsh/prompts/pro...

I'd also look at Mathias Bynens dotfiles repo.

Just use zsh with oh-my-zsh (https://github.com/robbyrussell/oh-my-zsh). Done.

Just wanted to say that. I hesitated for months before switching to zsh but here's a short presentation that sold me: http://www.slideshare.net/jaguardesignstudio/why-zsh-is-cool...

Speaking of git completion and branch info on the prompt, there are plugins in zsh for this and they're very easy to customize thanks to well-established conventions in oh-my-zsh.

It took me couple of hours to migrate from bash but it was time well spent.

Additionally to GIT_PS1_SHOWDIRTYSTATE the following are useful

  export GIT_PS1_SHOWUPSTREAM="auto"
  export GIT_PS1_SHOWSTASHSTATE=1
  export GIT_PS1_SHOWUNTRACKEDFILES=1

fish shell has some of this built in, such as the git prompt.

Here's a sample of my fish_prompt.fish

    function fish_prompt
      set last_status $status
    
      set_color $fish_color_cwd
      printf '%s' (prompt_pwd)
      set_color normal
    
      printf '%s ' (__fish_git_prompt)
    
      set_color normal
    end

export PS1=$LIGHT_GRAY"\u@\h"'$( g=$(__git_ps1 " (%s)") if [[ "$g" =~ \*\)$ ]] then echo "'$YELLOW'$g" elif [[ "$g" =~ \+\)$ ]] then echo "'$MAGENTA'$g" else echo "'$CYAN'$g" fi)'$BLUE" \w"$GREEN": "

function fish_prompt set last_status $status set_color $fish_color_cwd printf '%s' (prompt_pwd) set_color normal printf '%s ' (__fish_git_prompt) set_color normal end
