Add workable configuration for `Bash`, `Zsh` and `fish`:
Fish
cp $HOME/.pure/config/fish_prompt.fish $fish_config/functions/
echo 'set --global --export PURE_EXECUTABLE_PATH $HOME/.pure/' >> $fish_config/config.fish
exec fish
Zsh
cp $HOME/.pure/config/prompt.zsh $HOME/.zsh/
echo 'export PURE_EXECUTABLE_PATH=$HOME/.pure/' >> $HOME/.zshrc
echo 'source $HOME/.zsh/prompt.zsh' >> $HOME/.zshrc
exec zsh
Bash
mkdir ~/.bash/
cp $HOME/.pure/config/prompt.bash $HOME/.bash/
echo 'export PURE_EXECUTABLE_PATH=$HOME/.pure/' >> $HOME/.bashrc
echo 'source $HOME/.bash/prompt.bash' >> $HOME/.bashrc
exec bash
