#!./argv.sh        'a  b'  c   d          
# This illustrates the lack of proper argument parsing on the shebang line.
# The "argv.sh" script displays each command line argument on a separate line. 
# All the kernel does is remove leading and trailing blanks, but it doesn't
# split the string into separate pieces when it hands it to the command.
# If you look in the env(1) man page, you'll find it has an option to
# "process and split S into separate arguments; used to pass multiple
# arguments on shebang lines".  If you replace the shebang line above with:
#!/usr/bin/env -S ./argv.sh        'a  b'  c   d          
# then each argument will be properly parsed and handed to ./argv.sh
