I'm trying to debug a shell environment issue on a machine running lucid.
Both root & user have /bin/bash as their shell in /etc/passwd When I use "sudo su - user", my PATH includes the following directory: /usr/local/rvm/rubies/ruby-1.9.3-p194/bin/ruby when I "ssh user@machine" it has: /usr/local/rvm/rubies/ruby-1.9.2-p290/bin/ruby
Now, there are probably a number of ruby/rvm specific answers here -- that's not what I'm looking for, what I'm trying to understand is the general problem of where to look to find whatever it is that is setting the path. I know that /etc/profile gets executed, but it is being executed in both cases so I'm not sure what the issue is -- are there some other files that also get loaded on login -- in 1 case but not the other? / anything else that is being loaded that could be setting the PATH?
So it appears that something is happening before /etc/profile is loaded. I echo'd the environment on the first line of /etc/profile, and in the ssh case, the path already included a reference to /usr/local/rvm/rubies/ruby-1.9.2-p290/bin -- in the sudo su - case it did not. It appears that /etc/environment is used in the ssh case, but not the sudo su - case...
