    Add Executable Files to $PATH with Bash

    bashBash

    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.
