One of the purposes of this blog is a place where I can catalogue stuff and find it again later.  That is one of the purposes of this post.

I have multiple versions of Rails on my computer, and I wanted to create a new sandbox application with one of the older ones.  I didn’t know how to do it, until I found this post.

That post is more in-depth.  The quick and dirty is the command:

rails _<railsversion>_ <app name>

Example: rails _1.2.3_ test

Note that there is a space between “rails” and the first underscore, as well as one between the last underscore and “<app name>.”

Hat is off to you SIDDHARTH.
