(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.

Answer 1

You've installed the version of git-completion.bash from master - in git's development history this is after a commit that split out the __git_ps1 function from the completion functionality into a new file (git-prompt.sh). The commit that introduced this change, which explains the rationale, is af31a456.

I would still suggest that you just source the version of git-completion.bash (or git-prompt.sh) that is bundled with your installation of git.

However, if for some reason you still want to use this functionality by using scripts separately downloaded from master, you should download git-prompt.sh similarly:

curl -o ~/.git-prompt.sh \
    https://raw.githubusercontent.com/git/git/master/contrib/completion/git-prompt.sh

... and add the following line to your ~/.bash_profile:

source ~/.git-prompt.sh

Then your PS1 variable that includes __git_ps1 '%s' should work fine.

Geoff reported 10/13/12 adding the following to their .bash_profile worked while others did not:

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

Answer 2

After upgrading to OSX 10.9 Mavericks I had to reference the following files to get git shell command completion and git prompt to work again.

From my .bash_profile or similar:

if [ -f /Applications/Xcode.app/Contents/Developer/usr/share/git-core/git-completion.bash ]; then
    . /Applications/Xcode.app/Contents/Developer/usr/share/git-core/git-completion.bash
fi

source /Applications/Xcode.app/Contents/Developer/usr/share/git-core/git-prompt.sh

#shell prompt example
PS1='\u $(__git_ps1 "(%s)")\$ '

Answer 3

You should

$ brew install bash bash-completion git

Then source "$(brew --prefix)/etc/bash_completion" in your .bashrc.

Answer 4

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.

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.

High Sierra clean solution with colors !

No downloads. No brew. No Xcode

Just add it to your ~/.bashrc or ~/.bash_profile

export CLICOLOR=1
[ -f /Library/Developer/CommandLineTools/usr/share/git-core/git-prompt.sh ] && . /Library/Developer/CommandLineTools/usr/share/git-core/git-prompt.sh
export GIT_PS1_SHOWCOLORHINTS=1
export GIT_PS1_SHOWDIRTYSTATE=1
export GIT_PS1_SHOWUPSTREAM="auto"
PROMPT_COMMAND='__git_ps1 "\h:\W \u" "\\\$ "'

Answer 7

I had same problem when upgrading to Yosemite.

I just had to modify ~/.bashrc to source /usr/local/etc/bash_completion.d/git-prompt.sh instead of the old path.

then re-source your . ~/.bashrc to get the effect.

Answer 8

__git_ps1 for bash is now found in git-prompt.sh in /usr/local/etc/bash_completion.d on my brew installed git version 1.8.1.5

Answer 9

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 10

For macports I had to add: source /opt/local/share/git-core/git-prompt.sh to my ./profile

Answer 11

If you're hoping to use Homebrew to upgrade Git and you've let your system become out-of-date in general (as I did), you may need to bring Homebrew itself up-to-date first (as per brew update: The following untracked working tree files would be overwritten by merge: thanks @chris-frisina)

First bring Homebrew into line with the current version

cd /usr/local
git fetch origin
git reset --hard origin/master

Then update Git:

brew upgrade git

Problem Solved! ;-)

Answer 12

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 13

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 14

I know it's not a real answer...

I had some strange issues with sourcing git-prompt.sh in my .bashrc so I started to look for other solution. This one: http://www.jqno.nl/post/2012/04/02/howto-display-the-current-git-branch-in-your-prompt/ doesn't use __git_ps1 and author claims it works also on Mac (for now it works perfectly on my Ubuntu and it's easy to tweak).

I hope it helps!

I was doing the course on Udacity for git hub and was having this same issue. Here is my final code that make is work correctly.

# Change command prompt
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

source ~/.git-prompt.sh
export GIT_PS1_SHOWDIRTYSTATE=1
# '\u' adds the name of the current user to the prompt
# '\$(__git_ps1)' adds git-related stuff
# '\W' adds the name of the current directory
export PS1="$purple\u$green\$(__git_ps1)$blue \W $ $reset"

It works! https://i.stack.imgur.com/d0lvb.jpg

Answer 16

Please not that, if you haven't installed git through Xcode or home-brew, you'll likely find the bash scripts haysclarks refers to in /Library/Developer/CommandLineTools/, and not in /Applications/Xcode.app/Contents/Developer/, thus making the lines to include within .bashrc the following:

if [ -f /Library/Developer/CommandLineTools/usr/share/git-core/git-completion.bash ]; then
    . /Library/Developer/CommandLineTools/usr/share/git-core/git-completion.bash
fi

source /Library/Developer/CommandLineTools/usr/share/git-core/git-prompt.sh

You'll need those lines if you wish to use git-prompt as well. [1]: https://stackoverflow.com/a/20211241/4795986

Answer 18

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.

Answer 19

For git, there are /Applications/Xcode.app/Contents/Developer/usr/share/git-core/git-prompt.sh. And please look /etc/bashrc_Apple_Terminal too.

So, I put these in ~/.bash_profile:

if [ -f /Applications/Xcode.app/Contents/Developer/usr/share/git-core/git-prompt.sh ]; then
  . /Applications/Xcode.app/Contents/Developer/usr/share/git-core/git-prompt.sh
  export GIT_PS1_SHOWCOLORHINTS=1
  export GIT_PS1_SHOWDIRTYSTATE=1
  PROMPT_COMMAND="${PROMPT_COMMAND:+$PROMPT_COMMAND; }__git_ps1 '\u:\w' '\\\$ '"
fi

Answer 20

Yet another option I just installed on Mojave: magicmonty/bash-git-prompt

Run (brew update) and brew install bash-git-prompt or brew install --HEAD bash-git-prompt

Then to your ~/.bash_profile or ~/.bashrc:

if [ -f "$(brew --prefix)/opt/bash-git-prompt/share/gitprompt.sh" ]; then
  __GIT_PROMPT_DIR=$(brew --prefix)/opt/bash-git-prompt/share
  GIT_PROMPT_ONLY_IN_REPO=1
  source "$(brew --prefix)/opt/bash-git-prompt/share/gitprompt.sh"
fi

I'm happy.

Answer 21

Copy/Download the following files and copy them to home directory: ~/

git-completion.bash

git-prompt.sh

For the bash_profile, add this at the beginning:

source ~/git-completion.bash
source ~/git-prompt.sh
export GIT_PS1_SHOWDIRTYSTATE=1

For more and easy downloads you could check this.
