Is there a way to get the interactive ruby shell after running a script?

I would like to be able to use the created functions and objects I create in the script file, like python -i Thanks

IRB is the interactive shell so irb -r _path_to_file_

irb --help
Usage:  irb.rb [options] [programfile] [arguments]
  -f            Suppress read of ~/.irbrc
  -m            Bc mode (load mathn, fraction or matrix are available)
  -d                Set $DEBUG to true (same as `ruby -d')
  -r load-module    Same as `ruby -r'
  -I path           Specify $LOAD_PATH directory
  -U                Same as `ruby -U`
  -E enc            Same as `ruby -E`
  -w                Same as `ruby -w`
  -W[level=2]       Same as `ruby -W`
  --inspect     Use `inspect' for output (default except for bc mode)
  --noinspect       Don't use inspect for output
  --readline        Use Readline extension module
  --noreadline      Don't use Readline extension module
  --prompt prompt-mode
  --prompt-mode prompt-mode
            Switch prompt mode. Pre-defined prompt modes are
            `default', `simple', `xmp' and `inf-ruby'
  --inf-ruby-mode   Use prompt appropriate for inf-ruby-mode on emacs.
            Suppresses --readline.
  --simple-prompt   Simple prompt mode
  --noprompt        No prompt mode
  --tracer      Display trace for each execution of commands.
  --back-trace-limit n
            Display backtrace top n and tail n. The default
            value is 16.
  --irb_debug n     Set internal debug level to n (not for popular use)
  -v, --version     Print the version of irb

I dont know why yours didn't but here are all the options.

irb is the interactive ruby shell that comes with ruby. You can then use require 'file' to load the methods in a file, or you can do simply: irb -r module_name.
