My OSX setup, some bash functions and configurations used daily on my shell interactions.
To use add to your .bash_profile this:
BASH_LOAD_ROOT=/path/to/where/bash/project/is
. ${BASH_LOAD_ROOT}/load
Than load takes care of loading all functions, aliases and etc. Every directory defined in load will be sourced recursively.
Just cd into osx-setup folder and run ./setup.sh
This scripts and aliases are based on mavcunha/bash and adapted to my own needs.
