To append a directory named 'bin' that is in your home directory to your PATH, put this in ~/.bashrc
depending on whether or not the ~ or $HOME is easier for you to read in the future.
Will it work if I put that in .bash_profile? Also, how would appending my current working directory before appending bin work? Apparently by doing so, I should no
longer need to prefix ./ to execute something in my current directory.
