Answer 1

If you want to run shell commands inside controller just use "system"

Eg:

system "rails new test -d postgresql"

or else

exec "rails new test -d postgresql"

Answer 2

Use backticks to shell out, like this:
`rails new test -d postgresql`

It might be smarter to use a job queue for this.

Answer 3

To run command line statements inside controller, we can use system command

system "cd {path_to_folder}; rails new test -d postgresql"
