You don't need semicolons.
Ruby aims to be elegant and readable, so punctuation and boilerplate are
minimal.

Stick this in the bottom of ~/.profile & update PROJECT_BASE
Assuming you have a bunch of projects in PROJECT_BASE, you can do

bash> project my_project_name

You’ll now be in $PROJECT_BASE/my_project_name
Any new bash sessions you start will begin in that directory, which makes opening new tabs really convenient.
You can also just do

bash> project
