How can I reset $PATH in OSX? When I run:

echo $PATH


I get this:

/usr/local/bin:/usr/local/bin:/Library/Frameworks/Python.framework/Versions/3.5/bin:/usr/local/bin:/usr/local/bin:/Library/Frameworks/Python.framework/Versions/3.5/bin:/Library/Frameworks/Python.framework/Versions/3.5/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/git/bin


This is obviously completely messed up. So, how can I fix this or reset $PATH?

I'm running on El Capitan.
The default shell on OSX is bash. So you can set your path in .bash_profile or .bashrc file in your home directory.
