how to use rvm in shell scripting

Question

is it possible to load rvm in shell script . can any one give an example of it. when i try a shell script . i am using ubuntu system

#!/bin/bash
rvm use 1.9.3
         


        

Answer 1

for simply executing a command against a RVM managed Ruby (or system Ruby) do :

rvm 1.9.3 exec camper_van

this assumes rvm use 1.9.3 and gem install camper_van happened previously which provides the camper_van executable

NOTE: RVM is expected to be loaded already - which it usually is for scripts started under your user (the RVM is not a function, selecting rubies with 'rvm use ...' confirms it's there already).
