<div>
Unprivileged user cannot do this,<br />
<br />
either you need to use sudo (as an admin account) to run reboot /shutdown -r , or install this entry under the root user.<br />
Also be aware that the regular path is NOT available in active cron jobs.<br />
<br />
It is a good practice to qualify the command with full pathname.<br />
shutdown is also in /sbin which might not be in the default path...<br />
(You should receive a mail upon failure.)

cron and crontab problem

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.

Linux

Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.
