I need to add a new directory to my PATH so that SublimeText can find it. I assume this should be added to either .bash_profile, .bashrc, or .profile. Which one should I add it to? .bash_profile already has: export PATH=/home/josh/.rvm/gems/ruby-2.1.5/bin:/home/josh/.rvm/gems/ruby-2.2.0/bin:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATHin it..bashrc and .profile both have:export PATH=$PATH:$HOME/.rvm/bin in them. Should I have all of these in just one of the files and do multiple 'export' statements just get chained together when processed, even if from different files? 
How and where should I add a PATH?
