This is a minimal bash template using getopts for option parsing. It has a simple help menu and shows examples for how to get started. For more information on getopts, checkout the small getopts tutorial.
You can run shelly either by calling bash shelly [options] in the directory the shelly script is located in, by running chmod +x shelly to make it executable, then you can either run ./shelly [options] from within the same directory the shelly script is located, or you can move it into your /usr/bin/ directory with mv shelly lib /usr/bin/ and then you can call shelly -h for more information.

You can see in the shelly script the print_help function (located in the lib/functions.sh file is called. Note that this is sourced in the main shelly script on line 3.
