bash script with root privileges

[Perveance]

Hi all,

I have a script, which contains some privileged commands (sudo ifup eth0 etc). And I want run this script without entering root password. Is there a way I can do that? I heard about sticky bit and some other things that can do the trick...

Thanks in advance

I don't believe the modern kernel will allow you to setuid scripts, only binaries.

Just use sudo to do it - put an entry in sudoers for the user to run the script, and use the NOPASSWD option, e.g.:

joeblow ALL = (root) NOPASSWD: /path/to/superscript.sh

BTW, if running the script as root, you shouldn't need sudo commands inside the script itself.
