When reading the #! interpreter line variables in quotes "${FOO}" will
be evaluated and passed as a single argument to the command. Unquoted
variables like ${FOO} may result in multiple argument. For example,
if FOO="Hello World" that will result in two arguments "Hello" and
"World", where "${FOO}" will result in one argument "Hello World"
