PATH is a global environment variable that represents a list of directories bash looks in for executable files. The executable files for bash commands like grep are all somewhere on your OS’s PATH. We can add our own folders to PATH to make our executables available as a command to bash. In this lesson we’ll learn how to add a new folder to our PATH in .bash_profile and how to symlink an executable file into /usr/local/bin, which is in PATH by default.

Note that in zsh, when modifying your PATH you to provide an absolute path, ~ is not expanded.

Next time you echo your path, try this: echo $PATH | tr : '\n' | cat

Note: starting with Catalina, macOS now uses zsh as the default shell instead of bash. zsh and bash are very similar, but zsh looks for a .zshrc and .zprofile instead. See https://support.apple.com/en-us/HT208050 for more info on the differences between the two.
