How to build a custom command with options
I want to create a terminal short that takes me to a deeply-nested folder. For example, I just want to type in "star" every time I open the terminal to take me to cd source/alpha/beta/star.
I find it hard to believe this question hasn't been asked, but I can assure you haven't found the exact step-by-step solution. If you could let me know how to, or just point me to an existing answer, I'd appreciate.
