Ranjan, Rick and Ed Thank you for your input. I used the -f option with [olivares@localhost ~]$ crontab -l # min hour day-of-month month day-of-week command # 0-59 0-23 1-31 1-12 0-6 0=sun 1=mon 43 09 * * 1-5 ~/.dalarm >/dev/null 2>&1 33 10 * * 1-5 ~/.dalarm >/dev/null 2>&1 23 11 * * 1-5 ~/.dalarm >/dev/null 2>&1 13 12 * * 1-5 ~/.dalarm >/dev/null 2>&1 53 13 * * 1-5 ~/.dalarm >/dev/null 2>&1 43 14 * * 1-5 ~/.dalarm >/dev/null 2>&1 33 15 * * 1-5 ~/.dalarm >/dev/null 2>&1 33 16 * * 1-5 ~/.lalarm >/dev/null 2>&1 #10 17 * * 1-5 /usr/sbin/poweroff >/dev/null 2>&1 #20 17 * * 1-5 systemctl poweroff -f >/dev/null 2>&1 [olivares@localhost ~]$ To test the shutdown I used 10 17 * * 1-5 /usr/sbin/poweroff -f >/dev/null 2>&1 and with 20 17 * * 1-5 systemctl poweroff -f >/dev/null 2>&1 and none of these worked. I gave up and set this up as root and machine does shutdown. I wonder where Fedora changed things, it just worked TM, but now it does not. From your message Ed, I get that I would need to type a password, but if I issue the command(s) from terminal the machine shuts down and does not prompt me for anything. I was thinking also about /etc/cron.deny but one can do pretty much anything most were working except shutdown :( I created a file ~/.shutdown with the following: [olivares@localhost ~]$ cat .shutdown #!/bin/sh /usr/sbin/poweroff -f >/dev/null 2>&1 #systemctl poweroff -f >/dev/null 2>&1 [olivares@localhost ~]$ and called it within crontab, but it also failed to shutdown the machine. [olivares@localhost ~]$ cat /etc/fedora-release Fedora release 22 (Twenty Two) [olivares@localhost ~]$ uname -a Linux localhost.localdomain 4.1.6-201.fc22.x86_64 #1 SMP Fri Sep 4 17:49:24 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux [olivares@localhost ~]$ The permanent solution is to use root: [olivares@localhost ~]$ su - Password: [root@localhost ~]# crontab -l 58 21 * * 1-5 /sbin/poweroff > /dev/null 2>&1 [root@localhost ~]# and machine shuts down automagically at 9:58 pm at night :) Best Regards, Antonio A.
