The 'basename $0' returns the filename.

'basename' returns the filename string without any path info
eg. aFile instead of /aDirectory/anotherDirectory/aFile

$0 returns the first argument of a command line string, usually the command or appliction name

eg. cat someFile

$0 would return cat, $1 would return someFile
