Apple .command executed on mounted image

SOLUTION:

1. Create a command line program and make it execution clickable in Finder interface, by appending .command
   e.g. myexe.command
2. Wrap this up in a .dmg file, which is mountable once it is clicked on (it is how most mac programs are distributed from websites)

USAGE:

1. User clicks twice, once on the URL (e.g.) http://example.com/yoursoftware.dmg
2. User sees the mounted image in their Finder interface, and sees the (e.g.) myexe.command
3. User clicks on myexe.command

IMPLEMENTATION:

1. Create a shell executable.
   vi myshellscript.command
   #!/bin/bash
   ls -l
2. Make it executable.
   sudo chmod 0777 myshellscript.command
3. Put into directory as the only file.
   mkdir downloads
   mv myshellscript.command downloads/
4. Create a .dmg file
   hdiutil create -srcfolder downloads -volname MyDownloadable MyDownloadable
5. Click on MyDownloadable.dmg
6. Click on myshellscript.command
