I am not much of a Unix guy, but need to run one of my scripts as ROOT.
I believe I cn do it with SUDO (SUID being a risk), can someone help me how do I use SUDO stepwise.

TIA,
- Manish

Here is one of the great links that talks about setting up sudo files for permissions:

http://www.linuxhomenetworking.com/linux-hn/addusers.htm
http://www.courtesan.com/sudo/man/sudoers.html

Once you are setup with sudo, you need to run the script using the following syntax:

sudo sh - user -c command_or_script

Thanks
Vijay

um, that looks terribly insecure to me... i believe for that to work, you'd have to add /bin/sh to /etc/sudoers as a sudo-able command, wouldn't you? but that surely wouldn't be right, there's no end of ways the security of the shell could be breached.

i believe the "right" way to do this is to put the "command_or_script" into /usr/local/bin with root.root ownership, non-world-writable, and add that command_or_script only to /etc/sudoers. that way, you can run it as user with:

<pre>sudo -u user command_or_script</pre>

and let the system worry about the interpreter and its command line options.

It is sorta covered in the JavaRanch Style Guide.
