Most scripts won't execute as super user for good reason.
HOWEVER, you can get around this either by writing an suid C wrapper
program (basically just a C program that exec's your script) or by
using perl (which implements its own wrapper program).
I'd actually recommend either writing the script in perl or using a
perl script to call your shell script, as perl helps you avoid some
annoying insecure practices.
