In most (if not all) default OS X installations the script won't work (OK the script itself works but the command Something doesn't). The folder /usr/local/bin simply doesn't exist.
The folder /usr/local and all subsequent folders are reserved or designated for/to third-party commands.
Here are just a few examples of command line tools installed there by third-party app providers:
- MySQL Community Edition (Oracle)
- VirtualBox (Oracle)
- TextWrangler/BBEdit (links to a subsequent app folder)
To get the script running you have to install the command line executable .../Something residing in a subfolder of /usr/local first. The installed executable has to be compatible with the older system and all arguments/options in the script itself have to be compatible with the lower versioned (old) executable.
