Crontab - shell script as root

I have a shell script that needs to be executed once a day automatically. Every command within the script needs to be run as root.

How do I do this?

Add this to bottom of your /etc/crontab file. Just edit yours script in it. You can also change time when it's executed (this executes 05:00) ..

00 5 * * *  root /path/to/yours_script

do the following:

#crontab -e

and add the following line inside the crontab:

0 12 * * * /usr/share/bin/alarm would run a script called alarm every day at noon

To add, please make sure that

- All needed env variables are set in the script
- Use full path names of commands used e.g /usr/bin/ls
- Use full path names for files used e.g. /path/to/myfile
- Redirect output to log files e.g.

/usr/bin/command > /path/to/myscript.log 2>>&1
