  • [Bash] Add Executable Files to $PATH with Bash

    $PATH

    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.

    You can see the PATH:

    echo $PATH
    

    You can see one executable command where it located:

    which ng
    

    Add your executable command to the $PATH:

    export PATH="$PATH:~/my-scripts"
    

    Make the script:

    mkdir -p my-scripts
    echo 'echo hello' > my-scripts/hello
    chmod +x my-scripts/hello
    source .bash_profile
    

    Then run hello, you shoul see the output.

    Other way

    Another way to add an executable to $PATH is by symlinking an executable file into an existing folder that is always in $PATH.

    echo 'echo hello2' > my-scripts/hello2
    ln -s ~/hello2 /usr/local/bin
