Dan, on line 9 I think you want to pipe to ~/.zshrc.

Also, you can try using $0 to get the current prompt. I think that would be what you want, as $SHELL returns /bin/bash for me even I'm running zsh (but I didn't chsh)

$0 for bash will return bash, and $0 for zsh will return -zsh (not sure about the leading hyphen.)

if [ $0 -eq '-zsh' ]
  ...

What if divide this two script into one for bash and another one for zsh (Exact same script except zshrc->bashrc). And in the README.md tell the bash user to grab bash one, and vice versa. Maybe a simple solution to avoid possible error occurs.

I'm a fan of:

if [ -n "$ZSH_VERSION" ]; then
   # zsh
elif [ -n "$BASH_VERSION" ]; then
   # bash
else
   # error
fi

zsh does not always load ~/.profile, so I wouldn't depend on that.

And, as always, I question whether this script you're writing needs to be a bash script instead of normal POSIX.

This is probably just test code, but careful on line 6: you're missing a path separator

export PATH='/usr/local/bin/usr/local/sbin:$PATH'"

export PATH='/usr/local/bin:/usr/local/sbin:$PATH'"
