BASH OSX notes bash osx

Order of execution in OSX:

/etc/profile
~/.bash_profile
~/.bashrc
~/.bash_login
~/.profile
~/.bash_logout

For rvm to be happy, the order of PATH in .bashrc is important in OSX. The original way the PATH is set looks like: PATH=$PATH:$HOME/.rvm/bin. No, no. The PATH should be: PATH=$HOME/.rvm/bin:$PATH Note the trailing $PATH instead of leading.

Put aliases, source and custom prompt info in .bashrc.

From man bash:

When  bash  is invoked as an interactive login shell, or as a non-interactive shell with 
the --login option, it first reads and executes commands 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.  The --noprofile option may be used when the shell is started 
to inhibit this behavior.
