Some command-line tools for OS X will require you to add a new directory of base executables to your system path. Below, I'll outline the process of adding the directory
/usr/local/bin to the system PATH variable.
First, you'll need to edit the
~/.bash_profile file, or create it if it doesn't exist already.
$ sudo vi ~/.bash_profile
Once the file is open, add the following line.
After saving the file, run the following command to make sure
~/.bash_profile is executed.
$ source ~/.bash_profile
