[sudo-users] Passing the uid sudo was run by

[Paul Stepowski]

Hi list,

I was wondering if it's possible for a script to check which user sudo was run as.

e.g.

paul at box$ sudo ./my_script
original uid=509(paul)

Is there any way for ./myscript to know the original uid of the user who ran
sudo?  If so, can this be done in such a way that the uid cannot be manipulated
by the user running "sudo ./myscript"?

Thanks,

Paul
