2 Answers 2 2 Answers 2 16 It sounds like the environment necessary for the system to find the installed ruby components is specified in a file that only gets read for login shells. The bash manual page has this to say about the difference between login shells and non-login shells: INVOCATION A login shell is one whose first character of argument zero is a -, or one started with the --login option. and When bash is invoked as an interactive login shell, or as a non-inter‐ active shell with the --login option, it first reads and executes com‐ mands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. whereas When an interactive shell that is not a login shell is started, bash reads and executes commands from /etc/bash.bashrc and ~/.bashrc, if these files exist. Hence if the ruby environment variables are in /home/rails/.profile or /etc/profile for example, they will be added to the shell environment by explicitly invoking a login shell using su -l rails or su --login rails or the shorthand su - rails when user rails logs in via SSH by starting a subshell as bash --login after login If you want the ruby environment to be set regardless of how you switch to user rails, you could move the relevant variable definitions to the user's ~/.bashrc instead.

What are the relevant variable definitions? In what file are they written now? could you give me an example? This is a bit to theoretical. –  Apr 8 '14 at 19:27  |  7 I know that this question was asked 2 years ago, but in case if somebody (like me) still facing it: @steeldriver is right -- you are missing something in your bashrc which you do have in one of those 3 files. In my case I just needed to add this line into mine ~/.bashrc: [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" Follow answered Jul 7 '16 at 15:00 PepeHands 31744 silver badges1515 bronze badges  | Not the answer you're looking for?

Here’s how it works: fork { exec ("ls") } This will run ls on another process & display its output. Because this command is running in another process it will not block your Ruby app from running like the system method or %x.
