I need that Bash file to run periodically, and it must be as root.
Is that possible?
[root@file nutch-0.9]# locate crontab
/etc/crontab
/etc/sysconfig/crontab
/usr/bin/crontab
/usr/share/man/man1/crontab.1.gz
/usr/share/man/man1p/crontab.1p.gz
/usr/share/man/man5/crontab.5.gz
/usr/share/vim/vim71/syntax/crontab.vim
[root@file nutch-0.9]#

Like any other user, root has a user crontab. Essentially the same as any other user crontab, you are editing the root crontab when you run sudo crontab -e . Jobs scheduled in the root user crontab will be executed as root with all of its privileges.
To give root privileges to a user while executing a shell script, we can use the sudo bash command with the shebang. This will run the shell script as a root user. Example: #!/usr/bin/sudo bash ....
Yes, just add it to the root users' crontab; run the crontab -e command.
The places cron stores its files can be a little bizzare, so use the crontab -e command which will make sure it's in the right place, and I believe it checks the syntax.
