Question posted in 
I am not able to run reboot commands on my CentOS 7 machine.
For example I’ve created a script: /home/usr/myscript.sh (marked executable) with:
echo "hello world" > example.txt
When Im trying to run the script from terminal everything works good.
I tried to start the script on reboot at the end of the file:
nano /etc/crontab
I added:
@reboot /home/usr/myscript.sh
and on restart, nothing happen.
I also tried to edit file:
crontab -e
its looks like a new generated file, I’ve typed my command, and again nothing happend.
How can I run a command on CentOS at reboot?
I tried to insert that command on my Ubuntu machine, and everything was good and worked properly.
Anyone can advise on different way (maybe 3rd party program) that will help me to manage the reboot jobs?
Thanks for the help.
BTW, its might be duplicate, but I cant find any answer that helped me

I was able to reach this out by adding a crontab file for my user. with the following command: crontab -u usrname filename That allow me to run my scripts. Thanks !
In CentOS/RHEL 7, the systemctl utility replaces some older power management commands used in previous versions. The table below compares the older and new equivalent systemctl commands. The old commands listed in the table still exist for compatibility reasons.
Older Command systemctl equivalent Description
halt systemctl halt Halts the system
poweroff systemctl poweroff Powers off the system
reboot systemctl reboot Restarts the system
pm-suspend systemctl suspend Suspends the system
pm-hibernate systemctl hibernate Hibernates the system
pm-suspend-hybrid systemctl hybrid-sleep Hibernates and suspends the system
