Making bash script continue after exec $SHELL
I'm making a bash script that would install rbenv and ruby.
cd
git clone https://github.com/rbenv/rbenv.git ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL
git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL
rbenv install $rubyVersion
rbenv global $rubyVersion
But when the exec $SHELL is called the bash process is replaced by new bash process and the script stops (of course).
How can I make the script to continue?

execdoesn't mean "run this and wait for it to finish"; it means "run this and don't come back".

It appears that you're trying to achieve multiple objectives by modifying the .bashrc file then calling exec $SHELL. Neither of those actions will modify the shell-in-which-this-script-is-running. To modify the current shell, you want to "source" the .bashrc file. Use the "dot notation" instead of calling exec $SHELL:
. ~/.bashrc
Good luck with this one!
