Solaris 2.x:
Is there a way for a user to run a script, in which some commands are ran as root? Or for a user to run an entire script as root?
I want a user to be able to run some commands which only can be ran by the root, without having to give the root's password to the user...

Thank You.

That's what the setuid-flag is good for. Enter

chmod u+s <filename>

to allow any user to run <filename> as the owner of <filename>. If <filename> belongs to root, the command will be run as root.

Be careful, though, this is a dangerous feature, which may allow your users to hack your machine. DON'T create shell scripts which are suid root. Think carefully about which programs may be run as root safely, without giving the user too much power. Try to think of a way to avoid having your users run commands as root.
