Just out of curiosity: What is the "echo * |" supposed to do? From my
point of view the shell will expand "*" to the list of files and

This list is piped to sudo. But what does sudo do with these?

sorry, I didn't want to show my passwords, so I replaced it with an astrix. the password of course is being read from the pipe by sudo because of the -S option.

Probably nothing to do with your original problem, but you do know that you can allow sudo to execute certain commands without a password? Passwords in shell scripts isn't exactly ideal...

I am aware of the security issues, but in this case I think it's the best option because:

1) any one who can login to the machine also knows root passwords.
2) this script lives in a directory that is password protected by apache.
3) I don't like the thought of turning off passwords.
so if you can see the script, you won't learn anything you don't already know.
am I totally out to lunch?

E.g. my sudoers has:

Cmnd_Alias      HEALTHD = /usr/local/sbin/healthd

So anyone in group wheel (me :-)) can excecute any of the named commands without any password. You can also force the flags that will be passed - the sudoers man page has more details.
