sh: parse_git_branch: command not found

I have root enabled on osx El Captain. I tried some of the solution already provided on stackoverflow and supersu but couldn’t fix the error. I exported function parse_git_branch() to .bash_profile from .bash_prompt but I still get this error. I don’t know bash scripting so I have no idea what’s going on and what is to be fixed.

    The problem here is that when you do sudo su, you are changing to root but you are keeping your own profile. That profile contains a setting for the command prompt that references a bash function. But when you sudo to root, you are getting root’s shell, which is sh instead of bash – so any modifications that rely on bash configurations will not work, including the function you are referencing in your PS1.

    So, the first thing to do is to make sure that you are actually running bash instead of sh when you sudo. This is very simple – instead of running sudo su, you simply run sudo bash.

    Since sudo defaults to switching to root, you will now be running the bash shell as root, instead of just switching to the root user’s default shell.

    If you still have problems, this may be due to your .bash_profile containing a reference to the current user’s home directory, in that it points to ~ in these lines:

    for file in ~/.{path,bash_prompt,exports,aliases,functions,extra}; do
      [ -r "$file" ] && source "$file"
    done
    

    When you run bash as yourself, ~ will expand to your own home directory – but when you run it as root, it will evaluate to /var/root and that’s where it will look for your files.

    There are three ways you can fix this; choose whichever one you prefer.

    1. Change your .bash_profile so that it contains the full path to your home directory instead of just the tilde
    2. Copy all the related bash files to /var/root
    3. Instead of running sudo su, do sudo su -. This will give you root’s environment instead of your own. The downside is that all your own environment modifications will not be available to you, and you will be running sh instead of bash. (In some operating systems, those are the same thing, but in others it’s not. I believe that MacOSX is one of those where sh and bash are different things.)
