SHutdown without enetering password

[gunjannigam]

I want to close my system using a scipt. The scipt runs shutdown -h now to close the system but it needs root privileges. I dont want to enter the password every time on terminal. Is there a way that the commnad can be run with root privilege or the password could be saved in some file or in the scipt itself so that it does not asks for password each time I run the scipt. Please help

sudo chmod +s /sbin/shutdown 

gives superuser flag to shutdown

Edit the sudoers file:

sudo visudo

and append it with:

username ALL=(root) NOPASSWD:/sbin/shutdown -h now

replace usernaem with your login name.

HowTO: Sudoers Configuration

sudo chmod +s /sbin/shutdown

gives superuser flag to shutdown

It still asks for password

Do you still run "sudo" ?
Try:

shutdown -h now

Yaa I still use sudo
Without sudo it says you need to be root

sisco311 method worked thanks

yep,until you run:sudo chmod +s /sbin/shutdown,then it will not ask

but anyway sisco311's method is smarter.. at least on multiuser systems ...
