setuid bit on shell scripts - works? or not?

[Henry Spencer]

Given kernel support (4BSD, V8, maybe SysV) and a "#! /bin/sh" (etc) line
at the front, you can write setuid shell scripts.  They open up security
problems that can only be described as "disastrous", though.  If you have
any concern for security at all, setuid shell scripts are a serious mistake.
