(Mac) -bash: __git_ps1: command not found

Question

I'm trying to change my command promt in terminal. I keep getting the error:

-bash: __git_ps1: command not found

I've tried it just by typing it into the terminal as is: __git_ps1. I've also tried it out in the .bash_profile

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

As you might be able to see/tell, yes, I do have the auto-completion installed and it does work great!

I came across this question: " PS1 env variable does not work on mac " which gives the code

alias __git_ps1="git branch 2>/dev/null | grep '*' | sed 's/* \(.*\)/(\1)/'"

So I add it to my .bash_profile hoping that it will change something. Well, it did. It just changed the error output.

Here's the .bash_profile with the addition:

alias __git_ps1="git branch 2>/dev/null | grep '*' | sed 's/* \(.*\)/(\1)/'"

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

And now here's the changed error output:

sed: (%s): No such file or directory

Note: I've also moved the alias below the source with no difference. I have git version 1.7.12.1

This should be a simple change. Can someone please help me?

Edit 10/13/12

No, I definitely do not want to define __git_ps1 myself but was just trying to see if it would be recognized by doing so. Yes, I have the .git-completion.bash file installed. Here's how I got auto completion on my machine.

cd ~
curl -OL https://github.com/git/git/raw/master/contrib/completion/git-completion.bash
mv ~/git.completion.bash ~/.git-completion.bash

A ls -la then lists the .git-completion.bash file.

Edit 10/13/12 - Solved by Mark Longair (below)

The following code worked for me in the .bash_profile while others did not...

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

Answer 1

this works in OS 10.8 in the .bash_profile

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

Answer 2

Following worked for me like a charm:

Run following in your Terminal:

curl -L https://raw.github.com/git/git/master/contrib/completion/git-prompt.sh > ~/.bash_git

Open/Create bash_profile:

$ vi ~/.bash_profile

Add following to the file:

source ~/.bash_git
export PS1='\[\033[01;32m\]os \[\033[01;34m\]\w $(__git_ps1 "[%s]")\$\[\033[00m\] '
export GIT_PS1_SHOWDIRTYSTATE=1
export GIT_PS1_SHOWUPSTREAM="auto"

Finally, source it using:

$ source ~/.bash_profile

This will solve the problem of bash: __git_ps1: command not found.

Also your prompt will change to "os ". To change "os" to something else, modify "os" string in export PS1 line.

At least with Xcode 6, you already have git-completion.bash. It's inside the Xcode app bundle.

Just add this to your .bashrc:

source `xcode-select -p`/usr/share/git-core/git-completion.bash

Answer 4

1. Download the files git-prompt.sh and git-completion.bash from this Git completion
2. Rename the files.
3. Move those files to your home directory.

4. Add the source file in to the .bash_profile

   source ~/git-completion0.bash
   source ~/git-prompt0.sh
   and four to trigger the code block.
   

Answer 5

This one worked for me, and it has colored git output and an indicator in the prompt whether files have changed / been added, right baked into it:

GIT_PS1_SHOWDIRTYSTATE=true

. /usr/local/Cellar/git/1.8.5.2/etc/bash_completion.d/git-completion.bash
. /usr/local/Cellar/git/1.8.5.2/etc/bash_completion.d/git-prompt.sh

PS1='\[\033[32m\]\u@\h\[\033[00m\]:\[\033[34m\]\w\[\033[31m\]$(__git_ps1)\[\033[00m\]\$ '

Be sure to use the correct path! I used homebrew to install git, use brew list git to get the path to your current installation.

Would be nice not to use a hard coded path, but don't know how to get the path to the current installation.

Solution for MacOS Sierra and git version 2.10.1 <2017-2-06>

Step 1: Install the Git

You can skip this step if you already installed the latest git.

Download git package from browser https://git-scm.com/download/

Note: if you install with curl [option] https://... option to download, you would have to make sure your system support SSL. So for new comer, to download from browser and install directly from git installer is much easier.

Installation Verification:

• Show where is your git directory at: which git
• Show which version your git currently is: git --version current version should be 2.10.1.

Step 2: Add your git profile to your shell

1. Open your shell profile:
   • nano ~/.bash_profile or nano ~/.bashrc Depends on where your modification is.
2. Add the following code to the file:
   • source /usr/local/git/contrib/completion/git-completion.bash
   • source /usr/local/git/contrib/completion/git-prompt.sh

Note: git installation location changed from opt/ directory to usr/local/ after OSX upgrade to El Capitain, and this is why some of the old answer above doesn't work anymore in MacOS Sierra.

3. Add the following code to your PS1 configuration:

   • Option 1: add directly to your PS1: export PS1='\w$(__git_ps1 "(%s)") > '

     I prefer this simple approach since I already know the .git-completion.bash is there in my home directory, and I can add other prompt format in the front of it. here is my personal prompt for your reference: export PS1='\t H#\! \u:\w$(__git_ps1 "{%s}") -->> '

   • Option 2: Add a selection script

   if [ -f ~/.git-completion.bash ]; then
         export PS1='\w$(__git_ps1 "(%s)") > '
   fi

4. Save and use the profile: source ~/.bash_profile or source ~/.bashrc

Now you should see the git prompt working properly and shows which branch you are in right now.
